BACKGROUND: We report the second case of bladder neck artificial urinary sphincter (AUS) insertion in a child. Such a technique may have advantages in avoiding an open pelvic approach, improved visualization for patients with spina bifida and compact lower abdominal anatomy, and in decreased blood loss.
METHODS: A 7-year-old girl with lipomyelomeningocele presented with refractory gravitational incontinence. She had bladder-sphincter synergy, complete emptying on a uroflow, and was refractory to anticholinergics, botulinum toxin injection, biofeedback, a trial of pseudoephedrine, and even intermittent catheterization.
RESULTS: We performed a bladder neck AUS insertion robotically through a single camera port and one incision for each robotic arm. The important lessons from the case are that an anterior-only approach to the bladder neck works nicely robotically, and the traditional posterior and anterior approach may not be necessary or helpful. We performed all tubing connections through a port site; we removed the cannula, introduced the reservoir into the abdomen (it is too large to pass through a port), plugged the larger fascial incision with a 12mm traditional laparoscopic trochar, and placed the robotic cannula through the 12mm port. Lastly, whereas pump and tubing connections have previously been performed through a dedicated inguinal incision with the pump placed antegrade through this, we found it straightforward to place the pump in the manner of a laparoscopic orchidopexy, from the abdomen into the labia. The patient has continence except for extreme pelvic pressure (balance beam activities).
CONCLUSIONS: A robotic approach to AUS insertion works well, and only three incisions may be necessary. Antegrade, trans-pelvic pump placement through a port is simple, and a posterior approach may be avoided in some cases. <!--EndFragment-->
