[Long-term results following percutaneous pyeloplasty]

Area of Science:

• Urology
• Minimally Invasive Surgery

Context:

• Pyeloureteral junction obstruction affects numerous patients, necessitating effective treatment options.
• Traditional open surgery has been the standard, but minimally invasive techniques are gaining traction.

Purpose:

• To evaluate the long-term efficacy and safety of percutaneous pyeloplasty for congenital and secondary pyeloureteral junction obstruction.
• To compare outcomes with open surgery and identify factors influencing success rates.

Summary:

• A study followed 171 patients who underwent percutaneous pyeloplasty for pyeloureteral junction obstruction.
• Good to very good results were observed in 78% of patients, with better outcomes for primary, shorter stenoses and younger patients.
• Recurrences were managed successfully with repeat percutaneous procedures in most cases.

Impact:

• Percutaneous pyeloplasty is a safe endoscopic alternative to open surgery for primary obstruction.
• It should be the preferred initial approach for secondary pyeloureteral junction obstructions.
