Urinary Tract Calculi VI: Surgical Management

68
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Summary

A new distal one-stage urethroplasty technique effectively treats most distal urethral strictures without grafts or flaps. This approach offers shorter surgery times and avoids graft-related complications, with good outcomes.

Area of Science:

  • Urology
  • Surgical Techniques
  • Reconstructive Surgery

Background:

  • Distal urethral strictures present varied reconstructive challenges.
  • Existing treatments include meatotomy, grafts, or flaps.
  • A novel distal one-stage urethroplasty is presented.

Purpose of the Study:

  • To describe a contemporary cohort of distal urethral strictures.
  • To report a surgical technique, distal one-stage urethroplasty.
  • To evaluate the efficacy of this technique for distal urethral strictures.

Main Methods:

  • A cohort of 34 patients with distal urethral strictures was analyzed.
  • Mean patient age was 56.7 years, mean stricture length 1.1 cm.
  • Mean follow-up duration was 42.5 months.

Main Results:

  • 79.4% of strictures (27/34) were treated with the hybrid one-stage approach without grafts/flaps.
  • This approach involved scar excision, with average stricture length 0.68 cm and operative time 24.43 min.
  • Graft/flap use (7/34 patients) was associated with significantly longer stricture (2.88 cm) and surgery (154.8 min) (p < 0.001).
  • Recurrence rate was 17.6% (6/34), successfully treated with further repairs.

Conclusions:

  • Distal one-stage urethroplasty effectively treats most distal urethral strictures, often avoiding grafts/flaps.
  • This technique offers shorter operative times and reduced morbidity compared to graft/flap procedures.
  • Post-operative urine spraying is infrequent and comparable to other methods.
