Omental wrapping is a common cause of peritoneal catheter malfunction. This diagnosis should be confirmed by radiography before proceeding with surgical omentectomy. We report two cases of peritoneal dialysis (PD) catheter outflow obstruction from our developing PD program in Grenada, in which contrast studies accurately diagnosed omental wrap, allowing for prompt surgical correction. In both cases, the contrast study indicated the presence of omental wrapping, confirmed at time of surgical correction. Radiographic features of omental wrap are distinctive, which allows for reliable differentiation from other causes of obstruction. Radiographic contrast study reliably diagnoses the cause of peritoneal catheter obstruction, permitting prompt diagnosis and treatment. This is vital for regions with limited access to haemodialysis.

Department of Surgery, King Khalid University Hospital, Riyadh, Saudi Arabia.
Background: Obesity is an alarmingly increasing global public health issue. Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgery owing to its simplicity, effectiveness, and low complication rates. The complications can be classified as early or late, with fistula formation being one of the most severe complications.

The global rise in noncommunicable diseases, including chronic kidney diseases (CKDs), has led to a significant increase in the use of dialysis units to enhance patient longevity and quality of life. Over time, two-cuff catheters have been replaced by three-cuff catheters, with their usage expanding in nephrology centers across Saudi Arabia. This study aimed to evaluate the benefits, complications, and duration of therapy associated with three-cuff catheters in peritoneal dialysis (PD) patients.

Article Synopsis
- - The study reviews the effectiveness of the omentum in robotic-assisted reconstructive urology surgeries, highlighting its biological benefits and potential applications in complex procedures.
- - A systematic search of three databases yielded 13 relevant studies, covering various repairs, such as vesicovaginal and rectourethral fistulas, with recurrence rates between 0% and 6.7% and low complication rates.
- - The authors conclude that using omentum in robotic surgeries could be a safe and efficient option for complicated urological issues, but emphasize the need for more extensive studies to solidify its routine use in the field.

Background: The treatment of complex ureteral stricture has always been a hot and difficult topic in urology. The aim of our study is to investigate the feasibility and clinical efficacy of labial mucosal graft (LMG) onlay ureteroplasty without omental wrap for ureteral stricture with occlusion and present our initial experience.
Methods: We retrospectively reviewed perioperative and follow-up data of 12 patients admitted to The First Affiliated Hospital of Chongqing Medical University who underwent the LMG ureteroplasty with ureteral occlusion from April 2022 to September 2023.

Objective: To investigate the feasibility, safety and effectiveness of robot-assisted laparoscopic buccal mucosa graft ureteroplasty in the treatment of complex long proximal ureteral stricture.
Methods: The clinical data of 20 patients with proximal ureteral stricture undergoing robot-assisted laparoscopic buccal mucosa graft ureteroplasty admitted to the Department of Urology, Peking University First Hospital and Beijing Jiangong Hospital from July 2022 to January 2023 were prospectively collected and analyzed. Intraoperative conditions, postoperative complications and follow-up data were also recorded and analyzed.
