Project description:BackgroundTo summarize our experience with the Boari flap-psoas hitch and compare the indications, perioperative data and outcomes between open and laparoscopic procedures.MethodsThis study retrospectively reviewed 35 patients with complex distal ureteral stricture between January 2015 and April 2019. All patients were treated with Boari flap-psoas hitch by either an open or a laparoscopic procedure. Selection criteria were based on the etiology, comorbidities, medical history, and patient preference.ResultsAll surgeries were performed successfully. The median operation time was 201 min (range, 120 to 300 min), and the median estimated blood loss was 50 mL (range, 20 to 400 mL). The median postoperative hospitalization was 9 days (range, 3 to 46 days). Nineteen patients were treated by the open procedure, and 16 were treated by the transperitoneal laparoscopic procedure. The surgical indication of open surgery was broader than that for laparoscopic surgery. For patients experiencing iatrogenic injury and ureterovesical reimplantation failure, no significant differences in sex, laterality, operative time, ASA score or postoperative hospitalization stay were observed between the two groups. The median estimated blood loss was lower in the laparoscopic group than in the open group (P=0.047). Patients in the open group had more surgical complications than patients in the laparoscopic group (P=0.049). The postoperative follow-up showed the radiological resolution of hydronephrosis in 33 patients.ConclusionsWith the appropriate surgical considerations, Boari flap-psoas hitch is a valid method to bridge distal ureteral defects. For select patients, laparoscopic surgery had advantages being a minimal invasive surgery with less estimated blood loss and fewer surgical complications.

Project description:The treatment of ureteral stricture is a challenging task, especially when multiple strictures are present. Here, we report on a 63-year-old male patient diagnosed with hydronephrosis with left ureteral strictures who was admitted to our hospital. During treatment, a left percutaneous nephrostomy tube was inserted for hydronephrosis. Antegrade and retrograde pyelography were performed simultaneously. The results suggested there were 3 segment ureteral strictures in the left ureter: 2 located in the distal ureter and 1 in the proximal ureter. The treatment choices for multiple ureteral strictures are kidney autotransplantation or an ileal ureteral replacement (IUR), which are both morbid procedures and are technically challenging. With the excellent results of lingual mucosal graft (LMG) in ureteroplasty, this patient underwent a one-stage left ureter reconstruction with combined laparoscopic LMG ureteroplasty and ureterovesical reimplantation. However, disease of the oral mucosa and a reduced bladder volume caused by radio cystitis or chemical cystitis, may limit the use of this technique. Regular postoperative antegrade pyelography and the Whitaker test showed the unimpeded drainage of the left ureter. Based on the satisfactory outcome of this patient, combined laparoscopic LMG ureteroplasty and ureterovesical reimplantation for unilateral multiple ureteral strictures is a viable option that has fewer complications.

Project description:BackgroundThe treatment of bilateral long segment ureteral strictures is challenging. Minimally invasive bilateral ileal ureter replacement has been presented with limited experience. This study presents the results of the largest known sample size of minimally invasive bilateral ileal ureter replacement as well as the very first experience of minimally invasive bilateral ileal ureter replacement.Case descriptionFrom April 2021 to October 2022, nine cases of laparoscopic bilateral ileal ureter replacement for bilateral long-segment ureteral strictures were recruited from the database of RECUTTER. Patient characteristics, perioperative data and follow-up outcomes were gathered retrospectively. Success was defined as relieved hydronephrosis and a stable renal function without serious complications. All the nine patients underwent the procedure successfully without serious complications or conversion. The median stricture length of bilateral ureters was 15 cm (range, 8-20). The median length of the ileum used was 25 cm (range, 25-30). The median operative time was 360 minutes (range, 270-400). The median estimated blood loss was 100 mL (range, 50-300). The median postoperative hospital stay was 14 days (range, 9-25). At a median follow-up of 9 months (range, 6-17), all patients maintained stable renal function and showed improvement in hydronephrosis. Four postoperative complications were recorded, including three urinary tract infections and one incomplete bowel obstruction. No serious postoperative complications occurred.ConclusionsLaparoscopic bilateral ileal ureter replacement is safe and feasible for bilateral long-segment ureteral strictures. However, a large sample size with long-term follow-up is still needed to further demonstrate it as the preferred option.

Project description:To present our experience with laparoscopic ureteroneocystostomy with bladder flap (LUCBF) for treating benign ureteral stenosis and evaluate its feasibility and efficacy. The clinical data of 27 patients with benign ureteral stenosis who underwent LUCBF were retrospectively analyzed. After identification and excision of the ureteral stenosis segment, the healthy ureteral stump was dissected and incised longitudinally. A U-shaped or spiral bladder flap was harvested from the anterolateral bladder wall for ureteroplasty. All patients underwent LUCBF successfully, including 14 patients were combined with psoas hitch technique, between 90 and 220 min (median, 155 min). The median length of ureteral defect was 6 cm (range, 5-17 cm). The median blood loss was 40 ml (20-150 ml). The median indwelling time of double-J stent was 8 weeks (range, 4-8 weeks). Five patients (10.6%) suffered postoperative complications during the follow-up period (range, 12-48 months), including fever, hematuria, urinary tract infection and recurrent stenosis. The success rate was 96.3% (26/27). Patients with long ureter defects had longer operative time and more blood loss than short ureter defects. LUCBF was a safe and feasible technique for benign ureteral stenosis. Long ureter defect was related to longer operative time and more blood loss.

Project description:BackgroundComplete intracorporal robotic ileal ureteric replacement is challenging. We aimed to present the surgical technique of robotic ileal ureter replacement with extracorporeal ileal segment preparation for long ureteral strictures.MethodsFrom March 2019 to March 2021, 18 patients underwent robotic ileal ureter replacement with extracorporeal ileal segment preparation by one experienced surgeon. The demographic, perioperative, and follow-up data were recorded. Success was defined as the resolution of the presenting symptom, a stable estimated glomerular filtration rate and unobstructive drainage on imaging examination.ResultsAll 18 surgeries were successfully completed without conversion. The median length of the intestinal tube used was 20 (12-30) cm. The median operative time was 248 (170-450) min, the median estimated blood loss was 50 (10-200) ml, and the median postoperative hospital stay was 7 (5-27) days. At a median follow-up of 16 (13-28) months, all patients were symptom-free. No or mild hydronephrosis was confirmed in 17 patients; 1 patient had moderate hydronephrosis without peristalsis of the ileal ureter. The renal function was stable in all patients. The overall success rate was 100%. Postoperative complications, including 4 cases of urinary infections (Grade I), 1 case of an incision hernia (Grade I), 4 cases of kidney stone formation (Grade I), 6 cases of metabolic acidosis (Grade I), 4 cases of incomplete ileus (Grade II), and 1 case of an incision infection (Grade IIIb).ConclusionsRobot-assisted laparoscopic ileal ureter replacement with extracorporeal ileal segment preparation is safe, feasible, and effective for the treatment of long ureteral strictures, especially in high-volume tertiary referral centers with extensive robotic surgery experience capable of managing severe peri-operative complications.

Project description:Background and objectiveIn the last two decades, the treatment of vesicoureteral reflux (VUR) benefits from the introduction of robot-assisted laparoscopy surgery in pediatric population. This article aims to review the advantages of robot-assisted laparoscopic extravesical ureteral reimplantation (RALUR-EV) in pediatric patients with VUR and provides an update on surgical outcomes.MethodsA literature search of PubMed and MEDLINE databases was conducted. All the articles, published between 2010 and 2022, describing clinical outcomes of patients with VUR after treatment with RALUR-EV, were considered to be relevant for the purpose of the study. The results were synthetized as a narrative review.Key content and findingsTwenty-one studies were included. Of them, 19 (90.5%) presented a retrospective design. These articles involved 1,321 children and 1,914 ureters who underwent RALUR-EV. The mean age at the procedure was 6 years, and the mean follow-up length was 20.4 months. The overall success rate of surgery was 92.2% for patients and 90.9% per ureter. The mean operational time was 175.4 minutes for unilateral reimplantation and 200.3 minutes for bilateral reimplantation. The mean length of stay was 1.9 days.ConclusionsThe article discusses the adoption of RALUR-EV, its advantages, the heterogeneity of study protocols, and the evolution of surgical techniques. It also highlights the need for standardized protocols and prospective studies to further understand the advantages of RALUR-EV.
