Indications
- acute urinary retention
- recurrent urinary tract infection
- recurrent hematuria
- azotemia
- symptomatic bladder outlet obstruction
Contraindications
Radiographic features
Ultrasound or MRI
- irregular midline gap in the prostate at the bladder neck
- limited utility for evaluation of post-TURP anterior urethral strictures
RUG and VCUG
- VCUG shows a cone-like widening of the prostatic urethra
- RUG/VCUG good for evaluating possible post-TURP stricture
Complications
- hemorrhage (early)
- extravasation of irrigating fluid into the periprostatic tissue and the space of Retzius (early)
- development of a bladder neck contracture
- prostate regrowth
History and etymology
Transurethral resection of the prostate was developed in the 1920s and has been used continuously since that time. The number of TURP procedures has been decreasing with the advent of other minimally invasive therapies.
