Is High Drain Volume after Retropubic Radical Prostatectomy an Indicator of Bladder Neck Contracture Development?

Abstract

Aim: The aim of the present study was to evaluate if postoperative drain volume is a risk factor in bladder neck contracture development in patients who underwent retropubic radical prostatectomy.

Methods:The data of 151 patients who underwent radical retropubic prostatectomy by a single surgical team in our clinic between years 2015 and 2020 were analyzed. The demographic informations of patients, preoperative PSA level, prostate volume, Gleason score, pathological stage, operation time, estimated quantity of blood loss, drain removal time, drain volume, having postoperative urinary tract infection and incontinence development were evaluated.

Results:The drain volume of the group with BNC was 1960.23 ± 1492.4 ml while that of non-BNC group was 356.94 ± 624.3 ml. It was observed that postoperative drain volume of the BNC group was higher than the non-BNC group (p: 0.01). The mean time till to remove the drain was 8.04 ± 4.63 days in the group with BNC, while it was 3.54 ± 1.77 days. So the mean drain removal time was observed significantly longer in BNC group (p: 0.02).

Conclusion:The amount of post-operative drain volume is thought to be indicator of bladder neck contracture development.
