Abstract
OBJECTIVE
This study presents our initial experience with extraperitoneal and transperitoneal laparoscopic partial cystectomy (LPC) in the treatment of benign non-urothelial bladder tumors.
METHODS
Eleven patients with benign non-urothelial bladder tumors underwent extraperitoneal or transperitoneal LPC. The five cases with tumors located on the anterior/anterolateral bladder wall received the extraperitoneal approach. The six cases with tumors located around the bladder dome or over the posterior bladder wall received the transperitoneal approach. Key perioperative parameters were recorded.
RESULTS
All patients underwent laparoscopic resection smoothly without requiring a conversion to a traditional open procedure, and no patient displayed perioperative complications. Pathology showed benign non-urothelial bladder tumors with normal margins in all eleven patients, including five leiomyoma cases, three pheochromocytoma cases, two paraganglioma cases and one inflammatory fibrous histiocytoma case. Follow-up cystoscopy and imaging studies in all eleven patients (mean follow-up period 32 months) revealed neither residual nor local recurrence.
CONCLUSIONS
LPC is safe and feasible in select patients with benign non-urothelial bladder tumors and yields satisfactory oncological and functional results. Extraperitoneal LPC should be preferred for lesions located on the anterior/anterolateral bladder wall, while transperitoneal LPC should be preferred for lesions around the bladder dome or over the posterior bladder wall.
