Bladder neck contracture following transurethral resection of the prostate is a rare but feared complication. Treatment is often challenging with significant recurrence rates. In this report, we present a complicated case treated with a simple procedure. A 75-year-old male developed urinary retention due to bladder neck contracture after transurethral resection of the prostate. He was initially treated with several transurethral incisions, but the obstruction recurred few months after each incision. At urethroscopy, the bladder neck was completely obstructed. Using both retrograde and antegrade endoscopy, it was possible to place a through-and-through guidewire, after which the length of the stricture could be measured. Subsequently, the stricture was slightly dilated, and a double-cone thermo-expandable metal stent (Memokath 045) could be placed. The correct position was monitored with antegrade and retrograde endoscopy, securing the proximal cone expanded above the stricture and the distal cone above the sphincter. The patient was discharged the same day with spontaneous voiding and minimal residual urine. Twenty-one months after stent placement, the patient still had no complaints of his urination. Thus, the double-cone thermo-expandable metal stent, Memokath 045, may be a durable option for treatment of complicated bladder neck contracture after TURP for benign prostatic hyperplasia.
