Robot-assisted extravesical ureteral reimplantation: Outcomes and conclusions from 78 ureters
Journal of Pediatric Urology, 2014
Extravesical robot-assisted laparoscopic ureteral reimplantation (RALUR) is a popular alternative to open surgery. We report our experience with RALUR and evaluate clinical variables as predictors for failure. We retrospectively evaluated the records of patients who underwent RALUR by a single surgeon for treatment of primary vesicoureteral reflux. Clinical and demographic variables were determined. Clinical variables were compared with surgical outcomes using the Student two-tailed type 2 t test. Fifty patients underwent a combined 78 extravesical RALURs. Median (range) age was 6.2 (1.9-18.0) years; median (range) preoperative reflux grade was 3 (0-5). Dysfunctional elimination syndrome (DES) was present in 32 (64%). Ten (20%) patients had prior deflux, and two (4%) had prior ureteroneocystostomy on the ipsilateral side. Postoperative cystogram was performed in 100% at a median (range) of 55 (27-133) days. Median (range) follow-up was 286 (27-2238) days. Febrile urinary tract infection occurred in five (10%), none of whom had reflux on initial follow-up postoperative cystogram. All five had a history of DES and were female. Six complications occurred in five (10%) patients, including ileus (2), ureteral obstruction (2), ureteral injury (1), and perinephric fluid collection (1). Transient urinary retention occurred in one. Five of 22 (22.7%) patients undergoing unilateral surgery had contralateral de novo reflux. Six of 78 ureters (7.7%) had persistent reflux postoperatively. Neither persistent nor de novo reflux was associated with any of the clinical variables assessed. RALUR is an effective and safe option for patients with primary vesicoureteral reflux requiring surgery.

Purpose: To demonstrate our technical approach for robot-assisted ureteroneocystostomy (R-UNC) for benign and malignant distal ureteral pathologies. Materials and Methods: Between January 2009 and January 2013, a total of 10 patients underwent R-UNC in the distal ureter by a single surgeon. Indications for R-UNC were as follows: idiopathic (3), fistula (2), iatrogenic (2), malignancy (2), and chronic vesicoureteral reflux (1). Results: Tension-free anastomosis was attained in all 10 R-UNC procedures. A psoas hitch was performed in 6/10 cases (60%). Intravesical and extravesical reimplantations were completed in 5/10 (50%) and 5/10 cases (50%), respectively. A nonrefluxing ureter was constructed in 2/10 cases (20%). The patients' mean age was 52.9±16.6 years, their mean body mass index was 30.8±6.3 kg/m 2 , the mean operative time was 211.7±69.3 minutes, mean estimated blood loss was 102.5±110.8 mL, and mean length of stay was 2.8±2.3 days. There were no intraoperative complications. There was one Clavien-Dindo grade I and one Clavien-Dindo grade II postoperative complication. The mean postoperative follow-up duration was 28.5±15.5 months. Two patients had recurrence of ureteral strictures at 3 months postoperatively and were managed successfully with balloon dilation. Conclusions: Our technique for R-UNC demonstrates good perioperative outcomes. However, underlying periureteral inflammation and pelvic adhesions may predispose patients for stricture recurrence after R-UNC.
Expanding the Horizons: Robot-Assisted Reconstructive Surgery of the Distal Ureter
Journal of Endourology, 2009
Objectives: To report our single-center experience with robotic ureteroneocystostomy for the treatment of distal ureteral obstruction. Methods: We performed robot-assisted laparoscopic ureteroneocystostomies between May 2005 and October 2007. We retrospectively collected information on patient demographics, and compared renal scans with furosemide washout and radiographic imaging before and after repair to determine radiographic success. Statistical analysis was performed using statistical software via paired Student's t test analysis. Results: Eight robot-assisted laparoscopic ureteroneocystostomies on seven patients were performed over a 30month period. The etiology of the ureteric stricture was iatrogenic injury after hysterectomy in three patients, impacted stone in three, and infiltrative endometriosis in one. Mean stricture length was 2.2 cm. Right ureteroneocystostomy was performed in five patients and on the left in one, while one patient had bilateral disease. Mean operative time was 247 minutes (range 120-480), and average blood loss was 109 mL (range 50-200). Mean length of hospital stay was 2 days. All the procedures were completed successfully robotically without open conversion. Of the seven patients, one patient experienced recurrent symptoms. Subsequent imaging confirmed an anastomotic narrowing, which was treated by balloon dilation. There were no intraoperative or postoperative complications. Subsequent 99m Tc-mercaptoacetyltriglycine scans showed no evidence of obstruction. After a mean follow-up of 18 months (range 5-31), relative renal function of the entire group of patients improved after ureteroneocystostomy, although this did not achieve statistical significance (p ¼ 0.26). Conclusions: Robotic ureteroneocystostomy is a safe and effective treatment option for the management of distal ureteric stricture disease.

Background Management of recurrent ureteral stricture is challenging. Consensus on the best surgical choice has not been demonstrated. In this study, we aim to report our experience in treating recurrent ureteral stricture and demonstrate whether robot-assisted procedure for redo ureteral surgery is as effective as open procedure while remaining less invasive. Methods We retrospectively assessed 41 patients (22 robot-assisted surgeries and 19 open surgeries) who underwent consecutive robot-assisted and open procedures for redo ureteral surgery from January 2014 to 2018 in our institution. Perioperative outcomes, including demographics, operative time, estimated blood loss, complications, pain scores, success rate and cost, were compared between two groups. Results There was no significant intergroup difference in terms of age, body mass index, gender composition and American Society of Anesthesiologists scores. A total of 31 patients underwent redo pyeloplasty and ten underwent redo...
Robotic Approach to Ureteral Endometriosis: Surgical Features and Perioperative Outcomes
Frontiers in Surgery, 2018
Surgical treatment of ureteral endometriosis is necessary to relieve urinary symptoms of obstruction and to preserve renal function. Which surgical approach to ureteral endometriosis should be considered the most appropriate is debated, due to the lack of scientific evidence. The aim of the present study is to assess the feasibility and to describe the perioperative outcomes of minimally invasive treatment of deep ureteral endometriosis using robotic assistance, highlighting the technical benefits and the limits of this approach. Method: A case-series including 31 consecutive patients affected by high-stage endometriosis including ureteral endometriosis using robotic assistance in our Department between November 2011 and September 2017. Results: All procedures were successfully completed by robotic technique, resulting in full excision of the parametrial nodules involving the ureter. Mean operating time was 184.8 ± 81 min. Mean hospital stay was 4.02 ± 3 days. Perioperative complications occurred in five patients and 4 out of 5 involved the urinary tract. Conclusions: Robotic surgery for deep infiltrating endometriosis of the ureter was feasible and allowed complete resection of ureteral nodules in all cases. No intraoperative complications arose, but a non-negligible rate of urinary tract complications was detected. This calls for a careful assessment of the benefits and specific risks associated with the use of robotic surgery for the treatment of deep infiltrating endometriosis of the ureter.
Robotic Versus Open Ureteroneocystostomy: Is There a Robotic Benefit?
Journal of Endourology, 2020
Aim: We sought to compare the outcomes of patients who underwent an open vs robotic ureteroneocystostomy for ureteral obstruction. Methods: Retrospective review was performed on adult patients who underwent primary ureteroneocystostomy for obstruction from January 2012 to April 2018. Intraoperative outcomes of estimated blood loss (EBL) and operative time, as well as postoperative outcomes of catheter and stent duration, length of hospital stay, inpatient nurse-controlled opioid use, patient-controlled analgesia (PCA), and outpatient opioid prescription, complications, readmission, radiologic and clinical stricture recurrence, and follow-up, were compared. Among the open cohort, indications for an open approach were evaluated, identifying patients with prior complex open abdominal surgery that would make an open approach preferable. Results: Open ureteroneocystostomy was performed in 27 patients compared with 18 who underwent a robotic approach. The open and robotic cohorts were not significantly different in age, gender, Charlson comorbidity index, stricture location or side, abdominal surgery (laparoscopic or open), pelvic radiation, or preoperative urinary tract infection. The robotic group had a significantly lower rate of prior open abdominal surgery. The robotic cohort had significantly lower EBL, length of stay (LOS), catheter duration, prescribed morphine milliequivalents (MME) at discharge, and rate of PCA usage. Among the open cohort, 13 (48%) patients demonstrated indications making an open approach preferable. Comparing the robotic group with the remaining 14 open patients revealed a significantly lower rate of inpatient PCA use, prescribed MME at discharge, LOS, and catheter duration. Mean operative time was higher in the robotic group. EBL was not significantly different in this subanalysis. Conclusions: Robotic ureteroneocystostomy provides similar outcomes when compared with an open approach in well-selected patients when assessing for recurrent ureteral obstruction or adverse events. Robotic surgery is associated with lower postoperative narcotic pain prescriptions at discharge, lower PCA usage, and shorter LOS, which are important benefits when compared with open surgery.
Robot-assisted ureterocalycostomy: A single centre contemporary experience in adults
Arab Journal of Urology, 2016
Objective: To present our technique and experience of robot-assisted ureterocalycostomy (RAUC) in managing secondary pelvi-ureteric junction obstruction (PUJO) in adults. Patients and methods: We retrospectively reviewed all patients from our centre who underwent RAUC, between 2011 and 2015, for secondary PUJO resulting from previous surgical intervention. Six procedures in five patients, including a bilateral RAUC were performed. The median (range) patient age was 33.7 (18-41) years. The outcome variables included operative time, duration of hospital stay, and objective evidence of unimpeded drainage on urography. Results: The mean (range) operating time was 172 (144-260) min and estimated blood loss was 100 (50-250) mL. There were no conversions to open or laparoscopic surgery, and no intraoperative complications. Two patients had Clavien-Dindo Grade I complications that were managed conservatively and one patient had a Grade IIIb complication, which required balloon dilatation and re-stenting. After a median (range) follow-up of 11 (7-48) months, five of the six renal units had successful outcomes.

To present our experience and technique with robot-assisted ureteroneocystostomy (RAUN) procedure in adults. Methods: Between February 2015 and August 2018, a total of 30 (34 ureters) patients who underwent RAUN surgery under a single surgeon were retrospectively reviewed. Perioperative data such as age, sex, body mass index (BMI), American society of anesthesiologists score, estimated blood loss, surgical technique, operative time, complications, length of hospital stay, and stent removal time were recorded. During the follow-up, patients underwent renal function test, urinalysis, and renal ultrasound examination for evaluation. Success was defined as symptomatic and radiologic relieve. Lastly, a literature search was conducted to review all published articles regarding RAUN surgery in adults. Results: The patients' mean age, BMI, EBL, operative time, and follow-up period were 45.4 years, 23.1 kg/m 2 , 65.6 mL, 182.9 min, and 21.3 months, respectively. The two most common indications for the surgery were benign ureteral strictures and ureteric injuries secondary to a previous radical hysterectomy. Of the 34 cases, 26 (76.5%) and 8 (23.5%) patients received primary RAUN and RAUN with psoas hitch technique, respectively. Refluxing RAUN method was performed in all cases. No intraoperative complications were found. Two patients had a radiologic and symptomatic recurrence; one was managed with a repeat surgery while the other received ureteral dilatation treatment. Conclusion: Both our study and the published literature showed that RAUN is a safe, less invasive, and effective surgical technique that can easily replicate the open ureteroneocystostomy for managing lower ureteral diseases.
Robotic-assisted laparoscopic extravesical ureteral reimplantation: An initial experience
Journal of Pediatric Urology, 2012
Objective: There are many emerging techniques using robotic-assisted laparoscopy (RAL) in pediatrics. We performed a retrospective review of our first patients who underwent RAL extravesical ureteral reimplantation. a single surgeon performed RAL extravesical ureteral reimplantation in 17 patients. Six patients underwent bilateral reimplantation, resulting in a total of 23 ureters repaired. There were 16 females and 1 male (mean age 6.23 years). Four patients had prior Deflux injection. Postoperative reflux status was assessed by voiding cystourethrogram. Results: 16 patients (22 ureters) were compliant with follow up. Mean follow up was 11.5 months. Mean anesthetic time was 3 h, 57 min for unilateral and 4 h, 45 min for bilateral repair. Complete vesicoureteral reflux resolution was seen in 20 ureters (90.9%), downgrading in one ureter, and unchanged persistent reflux in one ureter. Average hospital stay was 1.3 days. No patients required postoperative catheterization at discharge. Conclusions: Outcomes for new procedures can be variable and unpredictable as the technique evolves. Given the high success rates of open reimplantation, a minimally invasive technique must show comparable results if it is to play a continuing role. Our initial results are encouraging, but prospective analyses are required to outline the future role of RAL ureteral reimplantation.
