Our objectives were to study and to evaluate thermotherapy for patients with retention of urine. The ‎ability of the patient to pass urine without significant post voiding residue was also studied. Eighty six ‎patients presented with urinary retention were treated by transurethral thermo therapy of the prostate, two ‎weeks following thermo therapy 55 patients (63.9%) were catheter free and by the third week only 9 ‎patients (10.4%) were still with catheter. It can be concluded that thermo therapy can be an option in the ‎treatment of urinary retention and keeping the catheter for one more week can raise its effectiveness
