Transurethral Microwave Thermotherapy (TUMT)

TUMT is one of a number of effective and safe procedures used in the treatment of lower urinary tract

symptoms (LUTS) caused by benign prostatic hyperplasia (BPH). TUMT provides an effective treatment for high surgical  risk patients with  LUTS. A safe  alternative treatment to prolonged  oral medications  like Alpha blockers and invasive procedures like transurethral resection of the prostate (TURP)

Procedure 

TUMT is an outpatient, non-surgical and minimally invasive therapy performed under a local anesthetic. The treatment involves inserting a special microwave urinary catheter into the prostatic urethra. The microwave antenna within the catheter is then heated to destroy the surrounding prostatic tissue.

The procedure lasts 30 minutes to one hour and  well tolerated by patients. After the procedure,  prostatic tissue will be swollen and irritated.A Foley catheter is inserted to prevent the patient from  urinary retention. After 3-5 days the catheter is removed.

Risks

– Urinary retention,  Infection and  mild to moderate pain or catheter discomfort.
– Evidence is turning in favour of TUMT over Transurethral resection of the prostate (TURP)

Aftercare

Post treatment convalescence is rapid, with most patients able to void and a mean recovery time of 5 days or more  at home. Prostatic swelling is expected after microwave therapy leading to a risk of urinary retention.  Foley catheter is  retained for 5 days up  to 2 weeks in all patients.  Urinary flow improves after a  month. Patients are maintained on alpha-blockers after TUMT and experience fewer urinary symptoms and have a decreased incidence of retention.
