Prolonged urinary leakage after partial nephrectomy: a novel management pathway.

Area of Science:

• Urology
• Surgical Innovation

Background:

• Prolonged urinary leakage is a challenging complication following partial nephrectomy.
• Existing treatments like ureteral stenting may be insufficient for persistent urinary fistulas.

Observation:

• A new endoscopic technique utilizing a Malecot catheter was applied to three patients with refractory urinary fistulas post-nephrectomy.
• Initial ureteral stenting failed to resolve the urine leak in these cases.

Findings:

• Placement of a Malecot catheter into the renal pelvis via a cystoscopic approach successfully achieved urinary drainage.
• All three patients experienced complete resolution of urinary leakage after the Malecot catheter stenting.
• Imaging at one month confirmed complete fistula healing with no reported infections or ureteral strictures.

Implications:

• This Malecot catheter technique offers a low-complication endoscopic solution for managing post-nephrectomy urinary fistulas.
• It serves as a valuable alternative to more invasive procedures like open surgery or percutaneous drainage.
• The method represents a significant advancement in the endoscopic management of complex urinary leaks.
