Urinary Tract Calculi VI: Surgical Management01:25

Urinary Tract Calculi VI: Surgical Management

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...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Nephrolithiasis Management

Background:

  • Percutaneous nephrolithotomy (PCNL) is a standard treatment for kidney stones.
  • Existing PCNL techniques can be invasive, requiring multiple steps for renal access and stone removal.

Purpose of the Study:

  • To evaluate the technical feasibility and safety of a novel 1-step percutaneous nephrolithotomy technique, termed microperc.
  • To assess the efficacy of microperc in treating renal calculous disease.

Main Methods:

  • Microperc was performed in 10 patients using a 4.85Fr all-seeing needle for simultaneous renal access and stone removal.
  • A flexible nephoscope and holmium:YAG laser fiber were utilized through the needle sheath.
  • Preoperative, intraoperative, and postoperative parameters were prospectively analyzed.

Main Results:

  • Microperc was technically feasible in all cases, with a high stone-free rate of 88.9% at 1 month.
  • The procedure demonstrated a low complication rate, with a mean hospital stay of 2.3 days.
  • Mean hemoglobin decrease was 1.4 gm/dl, and no auxiliary procedures were needed.

Conclusions:

  • Microperc is a technically feasible, safe, and effective minimally invasive option for small renal stones.
  • Further comparative studies are needed to establish microperc's role in treating non-bulky renal urolithiasis.
