Transperineal ultrasound-guided implantation of the prostate: morbidity and complications.

Two hundred and seventy four patients with early carcinoma of the prostate were treated by ultrasound-guided transperineal I-125 implantation. One hundred and ninety six received implant alone, and 78 were treated with combined external beam and I-125 implantation. Operative, early and late complications were reviewed with a median follow-up time of 40 months (minimum 13, maximum 64 months). Operative complications were negligible. Early morbidity (less than 12 months post implant) was noted in 10-15% of patients and consisted of self-limited irritative uropathy or obstruction. Late complications (more than 12 months post implant) were noted in 13%. Seven percent of patients had some combination of permanent sequelae of treatment: 14 patients had some degree of incontinence, 17 had irritative uropathy symptoms, and 7 had proctitis, 5 of whom resolved spontaneously. Most complications were mild to moderate with a notable absence of severe problems. Urinary morbidity was strongly related to prior or post-implant transurethral resection of the prostate (TURP) (24% with TURP, 3% without). Transperineal implantation in our experience is associated with an acceptable acute and chronic complication rate.
