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...

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Oncology

Context:

  • Renal cryotherapy is an emerging minimally invasive treatment for small renal tumors.
  • Selected patients with small renal tumors may benefit from this nephron-sparing approach.
  • Prior renal surgery in the treated or contralateral kidney presents complex cases.

Purpose:

  • To report the preliminary experience and outcomes of renal cryotherapy for small renal tumors.
  • To evaluate the safety and efficacy of laparoscopic renal cryotherapy.
  • To assess disease-free status and complications in patients undergoing renal cryotherapy.

Summary:

  • Eighteen patients with 21 small renal tumors (mean size 2.2 cm) underwent laparoscopic renal cryotherapy with a double freeze-thaw cycle.
  • Mean operative time was 196 minutes; 64% of patients experienced no complications.
  • At a mean follow-up of 46 months, 88.8% of patients were disease-free, with two developing metastatic disease.

Impact:

  • Encouraging results support renal cryotherapy as a viable minimally invasive option for nephron-sparing surgery.
  • This study represents one of the largest series of renal cryosurgery in Spain with substantial follow-up.
  • The findings contribute to the understanding of renal cryotherapy's role in managing small renal tumors in complex cases.
