title: 7-flap perineal urethrostomy.
abstract: Perineal urethrostomy (PU) has been performed with success for the treatment of refractory and advanced urethral stricture disease for at least the past six decades. Here, we review the indications and outcomes of PU for indications such as complex hypospadias repair and urethral stricture disease resulting from trauma, infection, and failure of prior urethroplasty. We also describe the role of 7-flap PU, a novel alternative to the conventional approach that offers the surgeon added flexibility in tailoring urethrostomy creation based on intraoperative findings. The authors' updated experience with 7-flap PU demonstrates a comparable 95% success rate in patients with a wide variety of stricture etiology. PU through either a conventional approach or a 7-flap technique is a valuable option for improving the quality of life in patients with debilitating urethral stricture disease.
