[Lithiasis and ectopic pelvic kidney. Therapeutic aspects]

Area of Science:

• Urology
• Nephrology
• Surgical Pathology

Background:

• Ectopic kidneys are often dysplastic and associated with other congenital malformations.
• The occurrence of urinary lithiasis in ectopic kidneys raises complex therapeutic questions.
• Pelvic ectopic kidney is a rare condition, further complicated by stone formation.

Purpose of the Study:

• To evaluate the therapeutic options for urinary lithiasis in patients with pelvic ectopic kidneys.
• To present surgical outcomes for treating kidney stones in ectopic renal tissue.
• To advocate for surgical lithotomy as a primary treatment modality.

Main Methods:

• Retrospective analysis of five cases of pelvic ectopic kidney with urinary lithiasis.
• Patients aged 16–42 years underwent surgical intervention.
• Procedures included total nephrectomy, pyelolithotomy, and associated pyeloplasty via a subperitoneal iliac approach.

Main Results:

• All five patients experienced successful outcomes with no recurrence at 6 and 12 months post-surgery.
• Kidney function varied, with two non-functional kidneys and others sized 10–12 cm.
• Surgical lithotomy demonstrated efficacy in stone removal and allowed for correction of associated anomalies.

Conclusions:

• Surgical lithotomy is a recommended and effective treatment for urinary lithiasis in ectopic kidneys.
• This surgical approach is technically feasible and facilitates the management of co-existing malformations.
• The procedure ensures a well-functioning kidney post-treatment with no stone recurrence.
