Laparoscopic excision of prostatic utricles in children.
OBJECTIVE
To report our experience of laparoscopic excision of symptomatic prostatic utricles in children.


METHODS
Prostatic utricles were excised laparoscopically in four boys (mean age 6.3 years, range 1.5-17). Cysto-urethroscopy and cannulation of the prostatic utricle was initially undertaken with a cystoscope that was left in situ inside the prostatic utricle to facilitate subsequent identification and mobilization during the laparoscopic procedure. Laparoscopy was conducted via a 5-mm port inserted through a supra-umbilical incision. Two more 5 mm working ports were inserted at the right and left mid-abdomen. The prostatic utricle was easily identified with the guidance of cystoscopic transillumination. Dissection was further facilitated by lifting and counter-traction of the prostatic utricle using the indwelling cystoscope. The prostatic utricle was completely mobilized and divided at its confluence with the urethra using an ultrasonic scalpel.


RESULTS
Laparoscopic excision of the prostatic utricle was successful in all four patients. The urethral defect was closed by intracorporeal suturing in three patients while the defect was small enough to be adequately closed by ultrasonic coagulation in one. One patient also had a nonfunctioning dysplastic kidney associated with an ectopic ureter joining into the prostatic utricle, and underwent nephroureterectomy at the same setting. The mean (range) operative duration was 148 (105-225) min. All four patients recovered uneventfully with no complications.


CONCLUSIONS
Laparoscopic excision under cystoscopic guidance is effective for symptomatic prostatic utricles, offering a good surgical view and allowing easy dissection in a deep and narrow pelvic cavity.
