[Transurethral partial cystectomy with a 2 micron laser in diagnosis and treatment for bladder submucosal lesions in adults].
OBJECTIVE
To investigate the characteristics of transurethral partial cystectomy with a 2 µm laser in diagnosis and treatment for the bladder submucosal lesions in adults.


METHODS
Nine patients with suspected pathological diagnosed bladder submucosal lesions in out-patient department were diagnosed and treated transurethral with a 2 µm laser under sacral block between August 2009 and December 2010. The diameters of tumors were 1.5 - 2.5 cm. A 2 µm laser was used to incise the full-thickness bladder wall around the tumors. The entire bladder wall was peeled between the detrusor muscle layer and outer connective tissues. Tumors with bladder wall at the base were removed together and sent for pathological examination. The surgical procedures, intraoperative hemorrhage, intraoperative and postoperative complications were observed, pathological diagnosis and postoperative follow-up were performed.


RESULTS
All operations were successful. Mean operative time was 36.4 minutes (range 25 to 47 minutes), perioperative blood loss was minimal. There was no obturator nerve reflection and no hemorrhage detected after surgery. Postoperative pathological diagnosis included leiomyoma in 3 cases, pheochromocytoma in 3 cases, endometriosis in 1 case and metastatic bladder cancer in 2 cases.


CONCLUSIONS
Transurethral partial cystectomy with a 2 µm laser can diagnose and treat bladder submucosal lesions. The procedures are effective and safe. Patients could get accurate pathological diagnosis without further painful and some bladder tumors can be treated by minimally invasive surgery.
