Erectile dysfunction is frequent among men with sleep disorders. Men with current sleep disturbances have also increased the risk for erectile difficulty in their future life. The correlation between sleep quality and erectile function and determinants of poor sleep quality among men who suffer from erectile dysfunction are still obscure. Near half of the men with erectile dysfunction are poor sleepers. Quality of sleep correlates with erectile function. Lean body mass, younger age, and severe depression are the main predictors of poor sleep quality.

With a high prevalence rate of Hypogonadism (HG), particularly pronounced in obese individuals, the research emphasizes the lack of a clear correlation between T levels, age, and symptom scores. It underscores the complexity of HG's diagnosis, given the absence of a universal T level threshold and the variable symptom presentation. By integrating commonly used symptom scores (IIEF-5 and AMS) for evaluation, the study contributes critical insights into the nuanced relationship between HG and obesity, advocating for targeted screening and management strategies in older males with high BMI. This research bridges existing knowledge gaps by clarifying the role of obesity as a key risk factor and questioning the reliance on age as a determinant of HG, thereby guiding more effective clinical assessments and interventions.

Between them, 30 claimed for moderate effect of therapy on item 1, 2 and 3a (3 points, differently to 1 score referred before treatment start). Between inclusion criteria, there was no other drug treatment in the same period. In this particular population, we tried to treat them by tradamixin once a day for 60 days. We evaluated ASEX questionnaire at the end of treatment. We considered a significant improvement in analyzed items return to 1 score. Results: 18 claimed of improvement in 3a items (group A, 60%), then 12 referred an enduring score of 3 or an increase of only one point (group B, no worsening has been referred after treatment). Increase in item 1 and 2 has been referred in a large amount of patients (25, 83%). Improvement has been always reported contextually in item 1 and 2. Interestingly, no difference has been reported in two different group A and B (15/18 in group A, 10/12 in group B, no statistical difference). Conclusion: Tradamixin could have a role and could be evaluated in treatment of mild or moderate iatrogenic sexual symptoms referred by patients treated with combination therapy for LUTS. In particular, effect on erectile disfunction is significant independently to effect on libido. This aspect could be strongly improved by Tradamixin. More data are needed, increasing sample size.

Participants, attending those settings during pregnancy, indicated how frequently they reached orgasm through sexual intercourse. Descriptive and regression analyses with a few chi-square tests were used to examine relevant factors. Results: Never reached orgasm during sexual intercourse are 13.7%, sometimes 41.4% and often 44.9%. Women at age less than 18 reached never orgasm in 2.9% of cases while 60% of them had often or very often orgasm. Those at age 18-25 reached never orgasm in 12% while women aged over 35 year never reached orgasm in 23.4%. The level of education show almost the same Results among participants who never reached orgasm ranged from 12.8% for those with university degrees to 15.2% of them with elementary school. The difference between smoking or not smoking women is very close 13.65 vs. 13.7%. Condom use is checked also and results are 13% for non users compared to 14.4% for users. Conclusion: The findings indicate that women differ from one another in terms of age only while other variables are without significance differences.

Our study aimed to determine T levels in the peripheral and cavernous blood taken during different penile conditions from healthy subjects and patients with ED. Methods: Blood was drawn during the penile stages of flaccidity, tumescence, rigidity (attained by the healthy males only) and detumescence from a cubital vein (CV) and the corpus cavernosum (CC) of 54 healthy males with normal erectile function and 46 patients with ED. Tumescence/rigidity was induced by audiovisual sexual stimulation. T (ng/ml plasma) was determined using a radioimmunoassay. Results: In the healthy individuals, T significantly increased in the cavernous blood during tumescence (2.9 to 4.3) and rigidity (4.4). In the phase of detumescence, T decreased to 3.5. In the systemic blood, the increase from flaccidity to tumescence was found to be less pronounced (4.1 to 4.4). From rigidity to detumescence, systemic T dropped slightly. In the patients, the increase in systemic and cavernous T levels from flaccidity (CV: 3.0, CC: 2.6) to tumescence (CV: 3.2, CC: 3.0) was less pronounced. In the flaccid phase, cavernous T in the healthy subjects was found to be 30% lower than the level in the peripheral blood, whereas, in the patients, this difference was only 13%. In patients with a psychogenic or organogenic cause of ED (n ¼ 13/20), the difference was 20% and 10%, respectively. Conclusion: In healthy subjects and ED patients, the difference between peripheral and cavernous T plasma levels in the flaccid phase, when blood flow through the penis is minimized, might represent a tool to calculate the amount of T that is available to exert androgenic effects in the CC.

In this study, we hypothesised that urine pH and perceived stress levels may differ in patients with BPS and that they may be related to each other. Materials and Methods: A prospective case-control study was conducted to test the hypothesis. Patients aged >18 years who were newly diagnosed with BPS were included in the patient group. The control group consisted of healthy volunteers aged >18 years. The 10-item Perceived Stress scale (PSS-10), spot urine pH measurements, Interstitial Cystitis Symptom index (ICSI), Interstitial Cystitis Problem index (ICPI), visual analogue scale for pain (VAS-Pain) and quality-of-life (QOL) scores were evaluated. Independent samples t-test and multivariate regression with path analysis were performed. Results: The study evaluated 84 patients with BPS and 86 healthy participants. The mean spot urine pH, PSS-10, ICSI, ICPI, VAS-Pain and QOL scores were different between the patient group and control group. Spot urine pH level [p=0.01, odds ratio (OR)=0.31] and PSS-10 scores (p=0.01, OR=1.1) remained significant predictors of BPS in the multivariate analysis. Lower urine pH and higher perceived stress levels were associated with worse ICSI, ICPI, VAS-Pain and QOL scores. Conclusion: Acidic urine pH and high perceived stress levels are associated with the presence of BPS. Perceived stress is independent from low urine pH, as they each relate to BPS symptoms in a bidirectional manner.

Methodology: After approval by the local ethics committee, all patients with nocturia ([?]1 nocturnal void/night) were included and filled the overactive bladder questionnaire (OABq), nocturia quality of life (N-QoL), ICIQ-MLUTS (male), ICIQ-FLUTS (female) and 3-day frequency-volume chart. Patients were divided into three groups according the severity of nocturia: group 1 consisted of patients with mild (1-2 voids/night), group 2 with moderate (3-4 voids/night) and group 3 with severe nocturia (>4 voids/night). Comparative analysis were performed between groups, p<0.05 was deemed as statistically significant. Results: 68.1%, 64.1% and 8.7% of the patients had nocturnal polyuria, reduced bladder capacity and global polyuria; respectively. 42.7% of the patients had mixed nocturia. 6.1% of the patients did not comply with the afore-mentioned subtypes and defined as isolated nocturia. Regarding the severity of nocturia; 155 (41%) patients had mild, 167 (45%) patients had moderate and 57 (15%) patients had severe nocturia. Increased nocturia severity was related with decreased quality of life; higher age, urinary tract symptom scores, nocturnal urine volume, evening fluid consumption and beta-blocker medication rates. Increased nocturia severity was also associated with higher nocturnal polyuria, global polyuria and reduced bladder capacity rates. Conclusions: Nocturia mechanisms may vary between mild and moderate to severe nocturia groups according to the present study. Nocturia grading with identification of subtypes may help for better standardization of the diagnostic and treatment approaches as well as for the design of future clinical trials.

Data sources: Clinical trial articles published in English on Medline. Eligibility criteria: Clinical studies that investigated the association of thyroid disorders with the ejaculatory function of subjects and the trials evaluating the effect of thyroid dysfunction treatment on the ejaculatory function of the subjects were eligible. Synthesis methods: We searched Medline with “ejaculation” and different combinations of “thyroid,” “serum TSH,” “serum T3,” “serum T4” keywords in PubMed. Results: Standardized mean serum thyroid-stimulating hormone (TSH) levels in premature ejaculation (PE) sufferers differed from non-PE control subjects (p=.05). Hyperthyroidism was associated with increased odds among PE subjects (OR=2.0, p=.03). Delayed ejaculation was seen with increased odds in hypothyroid patients ...

Objective: The aim of this study is to compare the efficacy and complications of holmium laser and pneumatic lithotripsy used in the ureterorenoscopic treatment of proximal ureteral stones. Materials and Methods: Data of 638 patients, who underwent ureterorenoscopy (URS) due to proximal ureteral stones in different centers, were obtained from patient files. The patients were divided into two groups according to the type of lithotripter used: group 1; laser lithotripter (n=324; 50.8%) and group 2; pneumatic lithotripter (n=314; 49.2%). URS was considered successful upon determination stone-free status with the imaging methods after treatment. The effectiveness and the complications of holmium:yttrium-aluminum-garnet laser and pneumatic lithotripsy were compared. Results: The total success rate of URS was 82.6% and the complication rate was 8.1%. The mean age of patients was similar between the groups; however, the body mass index values, stone surface area and stone Hounsfield unit were significantly higher in group 1. Although the mean operative time, complication rate and the mean length of hospital stay were similar between the groups; the URS success and postoperative ureteral Turkiye is an endemic region for urinary system stone disease and the incidence rate is 14.8%. Currently, ureterorenoscopy, where laser and pneumatic energy sources are used as lithotripter, is the first choice in the treatment of ureteral stones. The aim of this multi-centered study was to compare the efficacy of holmium laser and pneumatic lithotripters used in the ureterorenoscopic treatment of proximal ureteral stones and investigate their complications.

Objective: To analyze the effect of the anesthesia method (spinal and general) on the outcome of ureteroscopy (URS) in patients treated for proximal ureteral stones. Materials and Methods: Patients, who underwent URS for proximal ureteral stones at various urology clinics in Turkiye, were included in the study. The patients were divided into two groups according to the anesthesia method performed; the procedure was performed under spinal anesthesia (SA) in group 1 and general anesthesia (GA) in group 2. Patients' demographic, perioperative data and complication rates were compared between the two groups in a retrospective manner. Results: There were 309 and 329 patients in groups 1 and 2, respectively. The mean stone area and Hounsfield unit in GA group were higher (p<0.001 and p=0.007, respectively). In the GA group, the need for double J stent was more frequent (p<0.001). In the SA group, the rate of push-back of stone into the collecting system was higher (p=0.017). According to the Clavien classification system and the others, complication rates were similar between the two groups (p>0.05). The rate of success of URS, which is accepted as complete stone-free status, was higher in the SA group (p=0.041). Conclusion: URS, which is used in the treatment of proximal ureteral stones, has a high success rate, independent of the anesthesia method used. It is important to keep in mind the patient's comorbidities prior to selecting the anesthesia method and that the stone area and the Hounsfield unit are the important factors affecting the outcomes.

Objective: In this study it was aimed to search the efficacy of using polytetrafluoroethylene (PTFE) teflon felt for hemostasis on hemostasis and preventing urinary extravasation for patients who had open partial nephrectomy. Materials and Methods: Nineteen patients who were diagnosed with renal tumor in our clinic and underwent partial nephrectomy between December 2006-December 2008 were included to this study. All patients gave informed consent to participate to this study. Demographic characteristics of all patients were retrospectively evaluated. All patients were evaluated with their medical history, physical examination, urinalysis, blood tests, kidney and liver function tests and serum electrolytes. All the patients had abdominal ultrasonograhy and computed tomography or magnetic resonance imaging before surgery. Patients having abnormal renal function before surgery were not included in the study. All the patients had flank incision for open partial nephrectomy. The renal mass was removed by excision through blunt and sharp dissection with a 0.5-1 cm safety margin. The PTFE teflon strips (BARD ® , Teflon PTFE felt) with approximately 2 cm in width and 5 cm in length were placed into the two side of the removed material. Parenchyma was sutured with 0 vicryl ® and U fashion separately and renography was completed. Operation time and ischemia time were noted. Early period and postoperative 3-6 months patient follow-up were performed. Results: Mean age was determined to be 54.6 years. Mean tumor size was 4.8 cm (3-7, range). Mean operation time was 71 minutes. Warm ischemi time was 13.4 minutes. Mean hospitalization time was 3.5 days. Clavien grade-1 complication was seen in 10 patients. Ureteral catheter was not used in any patients. No postoperative prolonged drainage, fistula, urinary extravasation or hemorrhage seen in any patients. At postoperative 1 st and 6 th month follow-up, no delayed hemorrhage, fistula or liquid collection were observed. Conclusion: In partial nephrectomy, hemostatic suturing and renography with PTFE felt are effective and safe methods. Not seeing urinary extravasation but having efficient hemostasis may help patients with bigger tumor size to prefer partial nephrectomy.

Our study aimed to determine T levels in the peripheral and cavernous blood taken during different penile conditions from healthy subjects and patients with ED. Methods: Blood was drawn during the penile stages of flaccidity, tumescence, rigidity (attained by the healthy males only) and detumescence from a cubital vein (CV) and the corpus cavernosum (CC) of 54 healthy males with normal erectile function and 46 patients with ED. Tumescence/rigidity was induced by audiovisual sexual stimulation. T (ng/ml plasma) was determined using a radioimmunoassay. Results: In the healthy individuals, T significantly increased in the cavernous blood during tumescence (2.9 to 4.3) and rigidity (4.4). In the phase of detumescence, T decreased to 3.5. In the systemic blood, the increase from flaccidity to tumescence was found to be less pronounced (4.1 to 4.4). From rigidity to detumescence, systemic T dropped slightly. In the patients, the increase in systemic and cavernous T levels from flaccidity (CV: 3.0, CC: 2.6) to tumescence (CV: 3.2, CC: 3.0) was less pronounced. In the flaccid phase, cavernous T in the healthy subjects was found to be 30% lower than the level in the peripheral blood, whereas, in the patients, this difference was only 13%. In patients with a psychogenic or organogenic cause of ED (n ¼ 13/20), the difference was 20% and 10%, respectively. Conclusion: In healthy subjects and ED patients, the difference between peripheral and cavernous T plasma levels in the flaccid phase, when blood flow through the penis is minimized, might represent a tool to calculate the amount of T that is available to exert androgenic effects in the CC.

In this study, we hypothesised that urine pH and perceived stress levels may differ in patients with BPS and that they may be related to each other. Materials and Methods: A prospective case-control study was conducted to test the hypothesis. Patients aged >18 years who were newly diagnosed with BPS were included in the patient group. The control group consisted of healthy volunteers aged >18 years. The 10-item Perceived Stress scale (PSS-10), spot urine pH measurements, Interstitial Cystitis Symptom index (ICSI), Interstitial Cystitis Problem index (ICPI), visual analogue scale for pain (VAS-Pain) and quality-of-life (QOL) scores were evaluated. Independent samples t-test and multivariate regression with path analysis were performed. Results: The study evaluated 84 patients with BPS and 86 healthy participants. The mean spot urine pH, PSS-10, ICSI, ICPI, VAS-Pain and QOL scores were different between the patient group and control group. Spot urine pH level [p=0.01, odds ratio (OR)=0.31] and PSS-10 scores (p=0.01, OR=1.1) remained significant predictors of BPS in the multivariate analysis. Lower urine pH and higher perceived stress levels were associated with worse ICSI, ICPI, VAS-Pain and QOL scores. Conclusion: Acidic urine pH and high perceived stress levels are associated with the presence of BPS. Perceived stress is independent from low urine pH, as they each relate to BPS symptoms in a bidirectional manner.

Methodology: After approval by the local ethics committee, all patients with nocturia ([?]1 nocturnal void/night) were included and filled the overactive bladder questionnaire (OABq), nocturia quality of life (N-QoL), ICIQ-MLUTS (male), ICIQ-FLUTS (female) and 3-day frequency-volume chart. Patients were divided into three groups according the severity of nocturia: group 1 consisted of patients with mild (1-2 voids/night), group 2 with moderate (3-4 voids/night) and group 3 with severe nocturia (>4 voids/night). Comparative analysis were performed between groups, p<0.05 was deemed as statistically significant. Results: 68.1%, 64.1% and 8.7% of the patients had nocturnal polyuria, reduced bladder capacity and global polyuria; respectively. 42.7% of the patients had mixed nocturia. 6.1% of the patients did not comply with the afore-mentioned subtypes and defined as isolated nocturia. Regarding the severity of nocturia; 155 (41%) patients had mild, 167 (45%) patients had moderate and 57 (15%) patients had severe nocturia. Increased nocturia severity was related with decreased quality of life; higher age, urinary tract symptom scores, nocturnal urine volume, evening fluid consumption and beta-blocker medication rates. Increased nocturia severity was also associated with higher nocturnal polyuria, global polyuria and reduced bladder capacity rates. Conclusions: Nocturia mechanisms may vary between mild and moderate to severe nocturia groups according to the present study. Nocturia grading with identification of subtypes may help for better standardization of the diagnostic and treatment approaches as well as for the design of future clinical trials.

Objective: The aim of this study is to compare the efficacy and complications of holmium laser and pneumatic lithotripsy used in the ureterorenoscopic treatment of proximal ureteral stones. Materials and Methods: Data of 638 patients, who underwent ureterorenoscopy (URS) due to proximal ureteral stones in different centers, were obtained from patient files. The patients were divided into two groups according to the type of lithotripter used: group 1; laser lithotripter (n=324; 50.8%) and group 2; pneumatic lithotripter (n=314; 49.2%). URS was considered successful upon determination stone-free status with the imaging methods after treatment. The effectiveness and the complications of holmium:yttrium-aluminum-garnet laser and pneumatic lithotripsy were compared. Results: The total success rate of URS was 82.6% and the complication rate was 8.1%. The mean age of patients was similar between the groups; however, the body mass index values, stone surface area and stone Hounsfield unit were significantly higher in group 1. Although the mean operative time, complication rate and the mean length of hospital stay were similar between the groups; the URS success and postoperative ureteral Turkiye is an endemic region for urinary system stone disease and the incidence rate is 14.8%. Currently, ureterorenoscopy, where laser and pneumatic energy sources are used as lithotripter, is the first choice in the treatment of ureteral stones. The aim of this multi-centered study was to compare the efficacy of holmium laser and pneumatic lithotripters used in the ureterorenoscopic treatment of proximal ureteral stones and investigate their complications.

Objective: To analyze the effect of the anesthesia method (spinal and general) on the outcome of ureteroscopy (URS) in patients treated for proximal ureteral stones. Materials and Methods: Patients, who underwent URS for proximal ureteral stones at various urology clinics in Turkiye, were included in the study. The patients were divided into two groups according to the anesthesia method performed; the procedure was performed under spinal anesthesia (SA) in group 1 and general anesthesia (GA) in group 2. Patients' demographic, perioperative data and complication rates were compared between the two groups in a retrospective manner. Results: There were 309 and 329 patients in groups 1 and 2, respectively. The mean stone area and Hounsfield unit in GA group were higher (p<0.001 and p=0.007, respectively). In the GA group, the need for double J stent was more frequent (p<0.001). In the SA group, the rate of push-back of stone into the collecting system was higher (p=0.017). According to the Clavien classification system and the others, complication rates were similar between the two groups (p>0.05). The rate of success of URS, which is accepted as complete stone-free status, was higher in the SA group (p=0.041). Conclusion: URS, which is used in the treatment of proximal ureteral stones, has a high success rate, independent of the anesthesia method used. It is important to keep in mind the patient's comorbidities prior to selecting the anesthesia method and that the stone area and the Hounsfield unit are the important factors affecting the outcomes.

Objective: In this study it was aimed to search the efficacy of using polytetrafluoroethylene (PTFE) teflon felt for hemostasis on hemostasis and preventing urinary extravasation for patients who had open partial nephrectomy. Materials and Methods: Nineteen patients who were diagnosed with renal tumor in our clinic and underwent partial nephrectomy between December 2006-December 2008 were included to this study. All patients gave informed consent to participate to this study. Demographic characteristics of all patients were retrospectively evaluated. All patients were evaluated with their medical history, physical examination, urinalysis, blood tests, kidney and liver function tests and serum electrolytes. All the patients had abdominal ultrasonograhy and computed tomography or magnetic resonance imaging before surgery. Patients having abnormal renal function before surgery were not included in the study. All the patients had flank incision for open partial nephrectomy. The renal mass was removed by excision through blunt and sharp dissection with a 0.5-1 cm safety margin. The PTFE teflon strips (BARD ® , Teflon PTFE felt) with approximately 2 cm in width and 5 cm in length were placed into the two side of the removed material. Parenchyma was sutured with 0 vicryl ® and U fashion separately and renography was completed. Operation time and ischemia time were noted. Early period and postoperative 3-6 months patient follow-up were performed. Results: Mean age was determined to be 54.6 years. Mean tumor size was 4.8 cm (3-7, range). Mean operation time was 71 minutes. Warm ischemi time was 13.4 minutes. Mean hospitalization time was 3.5 days. Clavien grade-1 complication was seen in 10 patients. Ureteral catheter was not used in any patients. No postoperative prolonged drainage, fistula, urinary extravasation or hemorrhage seen in any patients. At postoperative 1 st and 6 th month follow-up, no delayed hemorrhage, fistula or liquid collection were observed. Conclusion: In partial nephrectomy, hemostatic suturing and renography with PTFE felt are effective and safe methods. Not seeing urinary extravasation but having efficient hemostasis may help patients with bigger tumor size to prefer partial nephrectomy.
