Ureteral injuries during photoselective vaporization of the prostate.

Photoselective vaporization of the prostate is a relatively new surgical modality for male lower urinary tract symptoms. The method has a risk of tissue damage if laser pulses miss the prostatic adenoma and travel through the irrigation fluid in the bladder. Five cases of damage to the ureteral orifices are described, with hidden orifices, intravesical prostatic adenomas and prior prostatectomy as risk factors for laser-related injuries to ureteral orifices. A laser-coagulated ureteral orifice does not seem to regain patency spontaneously, so rapid nephrostomy and subsequent DJ stenting is recommended.
