Laparoscopic reconstruction of iatrogenic-induced lower ureteric strictures: Does timing of repair influence the outcome?

CONTEXT: Influence of timing of repair on outcome following laparoscopic reconstruction of lower ureteric strictures

AIMS: To assess the influence of timing of repair on outcome following laparoscopic reconstruction of lower ureteric strictures in our adult patient population.

SETTINGS AND

DESIGN

Single surgeon operative experience in two institutes. Retrospective analysis.

MATERIALS AND

METHODS

All patients were worked up in detail. All patients underwent cystoscopy and retrograde pyelography prior to laparoscopic approach. Patients were categorised into two groups: early repair (within seven days of inciting event) and delayed repair (after two weeks). Operative parameters and postoperative events were recorded. Postprocedure all patients were evaluated three monthly. Follow-up imaging was ordered at six months postoperatively. Improvement in renal function, resolution of hydronephrosis and unhindered drainage of contrast through the reconstructed unit on follow-up imaging was interpreted as a satisfactory outcome.

STATISTICAL ANALYSIS USED: Mean, standard deviation, equal variance t test, Mann Whitney Z test, Aspin-Welch unequal variance t test.

RESULTS

Thirty-six patients (37 units, 36 unilateral and 1 simultaneous bilateral) underwent laparoscopic ureteral reconstruction of lower ureteric stricture following iatrogenic injury - 21 early repair (Group I) and 15 delayed repair (Group II). All patients were hemodynamically stable at presentation. Early repair was more technically demanding with increased operation duration. There was no difference in blood loss, operative complications, postoperative parameters, or longterm outcome.

CONCLUSIONS

In hemodynamically stable patients, laparoscopic repair of iatrogenically induced lower ureteric strictures can be conveniently undertaken without undue delay from the inciting event. Compared to delayed repairs, the procedure is technically more demanding but morbidity incurred and outcome is at par.
