Robotic assisted retrovesical approach to prostatic utricle excision and other complex pelvic pathology in children is safe and feasible.J Pediatr Urol. 2021 Oct; 17(5):710-715.JP
Excision of the prostatic utricle has been a challenging surgical problem due to the location deep in the pelvis between the rectum and bladder. Robotic-assisted laparoscopic surgery allows minimally invasive access to this location.
To describe the robotic surgical outcomes and important techniques associated with robotic excision of the prostatic utricle and explain how these techniques apply to similar pediatric pelvic pathology.
Retrospective chart evaluation of patients treated at a single institution with robotic excision of a prostatic utricle as well as two other patients in which the similar approach was employed.
4 patients underwent robotic excision of a prostatic utricle. A fifth patient underwent excision of urethral diverticulum that was the remnant of an ectopic ureter. The sixth patient had a high urogenital sinus that required laparoscopic assisted vaginoplasty approached in a similar manner to the above listed cases. Mean age at surgery was 35.5 months for the utricle patients. Mean follow-up duration for the utricle patients was 30.75 months. Average hospital stay for the utricle patients was one day. In the utricle patients one patient developed transient urinary retention and one had a postoperative urinary tract infection. Concomitant cystoscopy used in the two non-utricle patients was a key step in defining the proper location of dissection.
Robotic-assisted laparoscopic retrovesical excision of the prostatic utricle is a safe operation that requires a skill set that can be readily applied to other complex pelvic pathology such as the ectopic ureter, urethral diverticulum, and urogenital sinus. Concomitant cystoscopy can aid significantly in defining the location and limits of dissection.
