Research Article: The effect of pneumovesicoscopic Cohen surgery using a segmented submucosal tunnel and reduced intra-abdominal pressure for the treatment of vesicoureteral reflux in children
Abstract:
This study aims to explore the effect of using a segmented submucosal tunnel and reducing intra-abdominal pressure in the treatment of CO 2 leaking from the bladder into the abdominal cavity in vesicoureteral reflux (VUR) patients during pneumovesicoscopic Cohen surgery.
A retrospective analysis was conducted on children aged 0–1 years with VUR who underwent pneumovesicoscopic Cohen surgery at the Department of Urology, Fujian Children's Hospital from 1 May 2021 to 1 October 2024. Among them, 56 cases had CO 2 leakage from the bladder into the abdominal cavity during the surgery. The patients were divided into two groups based on the surgical method: Group A, 28 cases, where a submucosal tunnel was directly established during surgery, and Group B, 28 cases, where a submucosal tunnel was established in segments and decompression of the abdominal cavity was performed during surgery. Intraoperative and postoperative outcomes, complications, and clinical efficacy were compared between the two groups.
No complications from bladder leakage, anastomotic stenosis, or urinary retention occurred in either group after surgery, and no reoperations were necessary. In Group A, two cases were converted to open surgery, while no conversions were necessary in Group B. No statistically significant difference was found in indicators such as placement of the ureteral catheter, pain score (6?h after surgery), postoperative hospitalization time, conversion to open reimplantation, postoperative UTI, postoperative VUR, and postoperative hematuria time. The operation time (187.11?±?55.29?min vs. 157.79?±?44.96?min, P <?0.05) and pain score 2?h after surgery (2.21?±?0.79 vs. 1.39?±?0.99, P <?0.05) in Group B were lower than those in Group A.
Reducing intra-abdominal pressure combined with segmental submucosal tunneling is a simple, safe, and effective approach, which is recommended for managing CO 2 leakage from the bladder into the abdominal cavity of VUR patients during pneumovesicoscopic Cohen surgery.
Introduction:
Vesicoureteral reflux (VUR) is a common congenital disease of the urinary system in children with an incidence rate of approximately 1%–2%, and one of the most common causes of febrile urinary tract infection (fUTI) ( 1 , 2 ). VUR is the main cause of reflux nephropathy. Without active intervention, 10%–20% of children with reflux nephropathy will eventually develop hypertension and end-stage renal disease. The main goal of VUR treatment is to eliminate reflux, reduce the recurrence of urinary tract infection…
