Purpose: To describe and analyze a single surgical team's experience with intraoperative and postoperative complications arising from the Anderson-Hynes transperitoneal laparoscopic pyeloplasty (LP) procedure in the treatment of patients with ureteropelvic junction obstruction (UPJO).
Patients and methods: There were 236 consecutive patients who underwent transperitoneal LP over a period of 8 years (2004-2012). These patients' records were retrospectively analyzed for intraoperative and postoperative complications. Of the 236 patients, 111 (47.0%) were males and 125 (53%) were females. In 226 patients, surgical indication was primary UPJO, and in 10 patients, recurrent obstruction. Two hundred and eleven patients (89.4%) were symptomatic.
Results: Mean operative time was 96.5 minutes (range 45-360 min). The mean blood loss was 20 mL (range 5-500 mL), and no blood transfusions were necessary. The overall success rate was 97% (229 patients) with a mean follow-up of 38 months (range 6-84 mos). In 86 of the 94 patients who presented with a crossing vessel (91.5%), the anomalous crossing vessel was transposed to the ureteropelvic junction (UPJ) dorsally because of evident obstruction. The mean postoperative hospital stay was 4.2 days (range 3-14 days). All 211 preoperative symptomatic patients reported a complete resolution of symptoms after the procedure. Intraoperative incidents occurred in nine (3.8%) patients, while postoperative complications occurred in 32 (13.5%) patients.
Conclusions: Our retrospective analysis confirms that LP is an efficacious and safe procedure resulting in a reported success rate of 97% and a concomitant low level of intraoperative (3.8%) and postoperative complications (13.6%). Major complications necessitating active management occur in a low percentage of cases (5.9% of patients). The most frequent and severe intraoperative complications are related to the Double-J stent insertion. The most common postoperative complication is urine leakage.
