Delayed detection of injury to an ectopic ureter of a duplicated collecting system following laparoscopic radical prostatectomy for early organ-confined prostate cancer.

In the era of early detection of organ-confined prostate cancer, guidelines support the fact that many patients will not need an aggressive staging work-up, to avoid unnecessary investigations. This strategy may lead to serious repercussions in rare incidences. We present a rare case of urinary extravasation following laparoscopic radical prostatectomy caused by injury of the upper pole ectopic ureter of an undetected duplex system on 1 side, an injury which is the first of its kind in laparoscopic urology.
