transurethral resection of the prostate
Transurethral resection of the prostate (commonly known as a TURP, plural TURPs, and rarely as a transurethral prostatic resection, TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. This is considered the most effective treatment for BPH. This procedure is done with spinal or general anaesthetic. A triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. Outcome is considered excellent for 80-90% of BPH patients.
== Indications ==
BPH is normally initially treated medically. This is done through alpha antagonists such as tamsulosin or 5-alpha-reductase inhibitors such as finasteride and dutasteride. If medical treatment does not reduce a patient's urinary symptoms, a TURP may be considered following a careful examination of the prostate/bladder through a cystoscope. If TURP is contraindicated a urologist may consider a simple prostatectomy, in and out catheters, or a supra-pubic catheter to help a patient void urine effectively.〔(Collins, MD; Chief Editor: Edward David Kim, MD Transurethral Resection of the Prostate Medscape: )〕 As medical management of BPH improves, the numbers of TURPs have been decreasing.
