Patients and Methods: The clinical and follow-up data of the 4 patients with HPS (3 male, 1 female; age 39.7 ± 11.3 years) among 368 kidney transplant recipients during a 5-year period were retrospectively analyzed. Results: HPS developed 35–61 days in the post-transplant period. All 4 patients presented with fever. Hepatosplenomegaly and lymphadenopathy were observed only in the first patient. Laboratory tests revealed pancytopenia and hyperferritinemia in all patients, but elevated liver enzymes were observed in 3. Two patients had cytomegalovirus infection, and 1 had Epstein-Barr virus infection. Three patients died despite aggressive supportive therapy, however the fourth case survived after graft nephrectomy. Conclusion: HPS pathogenesis in kidney transplants appears to be related with the graft itself. Gra...

These problems are a cause of significant patient mortality and morbidity that have wide-ranging effects on graft survival throughout the entire life of the graft. Ultimately, the transplant comprises a major portion of the urinary system; therefore, the transplant team should be prepared for foreseeable and unforeseeable urological problems in the short and long terms. These mainly include postoperative urological complications (urine leakage, ureteral stenosis, and vesicoureteral reflux), bladder outlet obstruction, and graft urolithiasis. In recent years, significant advances have been made in the management of urological complications, especially due to advances in endourologic interventions. The aim of this review is to summarize the management of urological problems after kidney transplantation in the context of the current literature.

None of the patients had either hematologic or wound healing problems. Lymphoceles developed in eight patients. Serum creatinine level was 1.4 ± 0.5 mg/dL at 12 months. ...

Laparoscopic live donor nephrectomy (LLDN) provides an increase in donor numbers with its benefits and becomes a standard of care. We aimed to explain the results, complication rates, tips, and tricks of the largest number of LLDN case series ever performed in the literature. Materials and Methods: Between August 2012 and December 2019, 2,477 live donor case files were analyzed retrospectively. Age, gender, hospitalization times, body mass index, warm ischemia times, operation times, numbers of arteries, side of the kidneys, and complications were noted. Results: 1,421 (57.4%) of 2,477 donors were female (p = 0.007). Operation times and warm ischemia times were found longer in right-sided LLDN and donors with multiple renal arteries (p = 0.046, <0.001, and <0.001, respectively). Obesity (BMI >30 kg/m2) did not affect warm ischemia times while prolonging the operation tim...

Between 2009 and 2017, 31 patients who received stone-bearing (≤4 mm) kidneys were analyzed. At their last follow-up, the patients were evaluated with computerized tomography (CT) imaging and the results were compared to the initial CT findings obtained during donor evaluation. The mean stone size was 2.9 mm (range 1-4.3). The mean follow-up period after RT was 43.1 months (range 12-97). According to the CT findings of the last follow-up, the stone had passed spontaneously in 26 patients (83.9%). Three patients (9.6%) with a stone size of 4 mm required surgical intervention because the stone became symptomatic within the first year after transplantation. In the remaining 2 patients (6.4%), the stone remained in situ, without a change in its size. In terms of spontaneous passage rate, there was no significant difference between lower and midupper pole stones (P = ....

Between April 2009 and May 2016, BPH patients with renal transplants whose prostate volumes were less than 30 cm3 were treated surgically. Forty-seven patients received TURP and 32 received TUIP. The patients' age, duration of dialysis, duration between transplant and TURP/TUIP, preoperative and postoperative serum creatinine (SCr), International Prostate Symptom Score (IPSS), maximum flow rate (Qmax) and postvoidresidual volume (PVR) were recorded. At 1-,6- and 12-month follow-up, early and long-term complications were assessed. Results were evaluated retrospectively. In both groups, SCr, PVR and IPSS decreased significantly after the operation, while Qmax increased significantly (P < .001). There was no difference between the ...
