Urinary Tract Calculi VI: Surgical Management

343
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

526
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Procedures V: ERCP

2.6K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Summary

Retrograde laser endopyelotomy is an effective treatment for ureteropelvic junction obstruction (UPJO). While safe, further studies are needed to determine optimal laser sources for this minimally invasive procedure.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Endourology

Background:

  • Ureteropelvic junction obstruction (UPJO) causes hydronephrosis.
  • Retrograde endopyelotomy offers a minimally invasive approach for UPJO.
  • This review details retrograde laser endopyelotomy techniques, outcomes, and complications.

Purpose of the Study:

  • To review the technique of retrograde laser endopyelotomy.
  • To assess the outcomes and complications associated with this procedure.
  • To evaluate its efficacy as a treatment for UPJO.

Main Methods:

  • Comprehensive literature review conducted in June 2025.
  • Searched MEDLINE and Scopus databases without time or language restrictions.
  • Adhered to PRISMA system guidelines for systematic reviews.

Main Results:

  • Overall success rates ranged from 44% to 89% (mean 77.2%) using Holmium:YAG lasers.
  • Mean follow-up was 23.2 months; most complications were minor (Clavien grade I).
  • Short hospital stays (1-3 days) were typical; success definitions varied across studies.

Conclusions:

  • Retrograde laser endopyelotomy is a safe and effective treatment for UPJO.
  • It is currently considered a second-line treatment option.
  • Comparative studies, including Thulium lasers, are necessary to establish the optimal laser for endopyelotomy.
