Abstract
PURPOSE Successful treatment options for ureteral strictures are limited. Surgical options such as ileal interposition and kidney autotransplantation are difficult and associated with morbidity and complications. Techniques such as Boari flap and psoas hitch are limited to distal strictures. Only limited case studies on the success of open buccal mucosa graft (BMG) ureteroplasty exist to this date. The purpose of this study was to evaluate the success of open BMG ureteroplasty without omental wrap. METHODS In this single-center retrospective study between July 2020 and January 2023, we included 14 consecutive patients with ureteric strictures who were treated with open BMG ureteroplasty without omental wrap. The primary outcome was the success of open BMG ureteroplasty. Further endpoints were complications and hospital readmission. Outcome variables were assessed by clinical examination, kidney sonography, and patient anamnesis. RESULTS Out of 14 patients, 13 were stricture and ectasia-free without a double-J stent at a median follow-up of 15 months (success rate 93%). No complications were observed at the donor site, and the complication rate overall was low with 3 out of 14 patients (21%) having mild-to-medium complications. CONCLUSIONS Open BMG ureteroplasty without omental wrap is a successful and feasible technique for ureteric stricture repair.

Abstract
Ureteral strictures can occur along the entire course of the ureter and have many different causes. Factors involved in the development include, among other things, congenital anomalies, iatrogenic injuries during endoscopic as well as open or minimally invasive visceral surgical, gynecological, and urological procedures as well as prior radiation therapy. Planning treatment for ureteral strictures requires a detailed assessment of stricture and patient characteristics. Given the various options for ureteral reconstruction, various methods must be considered for each patient. Short-segment proximal strictures and strictures at the pyeloureteral junction are typically surgically managed with Anderson-Hynes pyeloplasty. End-to-end anastomosis can be performed for short-segment proximal and middle ureteral strictures. Distal strictures are treated with ureteroneocystostomy and are often combined with a Boari and/or Psoas Hitch flap. Particularly, the treatment of long-segment strictures in the proximal and middle ureter remain a surgical challenge. The use of bowel interposition is an established treatment option for this, offering good functional results but also potential associated complications. Robot-assisted surgery is increasingly becoming a minimally invasive treatment alternative to reduce hospital stays and optimize postoperative recovery. However, open surgical ureteral reconstruction remains an established procedure, especially after multiple previous abdominal operations.

A New Application of an Old Technique. Res Rep Urol 2022; 14:351-358. [PMID: 36246791 PMCID: PMC9562977 DOI: 10.2147/rru.s371856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Accepted: 08/13/2022] [Indexed: 11/06/2022] Open
Abstract
Objective To describe our new endoscopic approach in treating iatrogenic ureteral stenosis using the “cut-to-The-light” technique. Methods Case of a 54 year-old female patient who underwent a right percutaneous nephrolithotomy to treat a staghorn calculus with two subsequent complimentary ureteroscopies complicated by a severe proximal ureteral obstruction. An antegrade flexible uretereroscope and a retrograde rigid ureteroscope were used to locate the stenosis. With the aid of a 365-µm Ho: YAG laser fiber (settings 0.4 J, 12 Hz), we managed to successfully create a small incision in the stenotic lesion, the rigid ureterscopy light was clearly seen by the antegrade flexible ureteroscope and a through-and-through guidewire was then placed, securing the ureter. Ureteral dilatation was then performed followed by a full thickness incision of the ureteral stenosis. A single 8Fr, 28 cm double J ureteral stent was finally placed after stone fragmentation. Results The operating time was 200 mins. No blood loss. No fever or signs of UTI were seen shortly after the operation. The Foley catheter was successfully removed at day one post-op. The hospital stay was short of only 2 days. Conclusion The “cut-to-the-light” technique is a new application in the arsenal of ureteral stricture treatment that has been scarcely described in the literature before. The use of this method seems to offer excellent outcomes thus demonstrating the importance of this minimally invasive technique as an alternative to conventional invasive methods used. We believe that studies with larger samples and longer follow up are needed in order to fully determine the benefits of this method and to assess and reveal its suitable application and its drawbacks.
