ABSTRACT
The aim was to analyze the operative, postoperative and functional outcome of laparoscopic management of previously failed pyeloplasty and to compare operative and postoperative outcome with laparoscopic pyeloplasty for primary ureteropelvic junction obstruction [UPJO]. All patients who underwent laparoscopic management for previously failed dismembered pyeloplasty were analyzed in this study. Detailed clinical and imaging evaluation was performed. Transperitoneal approach was followed to repair the recurrent UPJO. Operative, postoperative, and follow-up functional details were recorded. Operative and postoperative outcomes of laparoscopic redo pyeloplasty were compared with that of laparoscopic primary pyeloplasty. A total of 16 patients were managed with laparoscopic approach for previously failed pyeloplasty. Primary surgical approach for dismembered pyeloplasty was open in 11, laparoscopy in four patients and robotic assisted in one patient. Fifteen were treated with redo pyeloplasty and one with ureterocalicostomy. Mean operative time was 191.25 +/- 24.99 min, mean duration of hospital stay was 3.2 +/- 0.45 days and mean follow-up duration was 29.9 +/- 18.5 months with success rate of 93.3%. Operative time was significantly prolonged with redo pyeloplasty group compared with primary pyeloplasty group [191.25 +/- 24.99 vs. 145 +/- 22.89, P = 0.0001]. Laparoscopic redo pyeloplasty is a viable option with a satisfactory outcome and less morbidity
ABSTRACT
Wharton's jelly is a specialized tissue which acts as supportive and protective structure substituting for the adventitia of the umbilical vessels. Absence of Wharton's jelly around the umbilical arteries is very rare and an unusual cause of perinatal mortality. We report a case of absent Wharton's jelly around the umbilical arteries with patent vitellointestinal duct--a rare association.
