Abstract:
Objective:To investigate the efficacy of single-port intravesical laparoscopic Politano-Leadbetter in the treatment of adolescent primary obstructive megaureter.Methods:Retrospective analysis was performed on the clinical data of 11 adolescents with primary obstructive megaureter who received single-port intravesical laparoscopic Politano-Leadbetter in Fujian Provincial Hospital from January 2018 to November 2019, including 7 males and 4 females, 8 patients with left stenosis and 3 patients with right stenosis. The mean age was (13.5±2.4) years old, and the mean weight was (49.4±11.2) kg. Before surgery, the anteroposterior diameter of the affected renal pelvis was (3.25±0.69) cm, the maximum diameter of the ureter was (2.25±0.48) cm, the thickness of the affected renal cortex was (1.34±0.52) cm, and the renal function was (36.00±2.86) %. All patients underwent Politano-Leadbetter by single-port intravesical laparoscopic. Suprapubic bladder approach was used to establish a single-hole air bladder channel, and the end of the ureter was dislocated and cut, the submucosal tunnel of the bladder was established, and the end of the ureter was re-embedded. The Politano-Leadbetter ureteral replantation was completed.The dilatation and tortuousness of the affected renal pelvis and ureter and the changes of renal function of the affected kidney were analyzed before and after operation.Results:All operations were completed successfully.The operative time was (95.6±18.5) min, the intraoperative blood loss was (6.8±2.3) ml, the postoperative indwelling catheter time was (4.5±1.8) d, and the average hospital stay was (6.2±2.4) d. Postoperative follow-up time was (13.6±4.3) months.12 months after surgery, the anteroposterior diameter of the affected renal pelvis and the maximum diameter of the ureter were (2.00±0.45) cm and (1.18±0.22) cm, which were significantly lower than those before surgery ( P< 0.05). The thickness of the renal cortex was (2.17±0.49) cm, and the renal function was (44.00±1.41) %, which was significantly increased compared with that before operation ( P<0.05). Diuretic nephrogram showed no mechanical obstruction or no obstruction curve. One patient developed urinary tract infection 6 weeks after operation and recovered after removal of double J tubes.The other patient presented degree I ureteral reflux 6 months and 1 year after surgery, without urinary tract infection and low back pain.All the other children recovered well without postoperative complications.All parents were satisfied with the incision. Conclusions:Single-port intravesical laparoscopic Politano-Leadbetter for the treatment of adolescents with primary obstructed megareter can improve hydronephelectasis of the renal pelvis and renal function of the affected kidney, and overcome the difficulty of injury due to fat pad hypertrophy in the bladder area above the pubic bone and the establishment of conventional pneumo-bladder laparoscopy, the operation effect is ideal, few complications, safe and feasible.
