[Right ectopic hydronephrotic kidney with pelvic lithiasis. Report of a case].

OBJECTIVE

To report a case of hydronephrotic ectopic kidney with lithiasis and pelvic localization, its diagnostic aspects and surgical treatment.

METHODS/

RESULTS

A 39-year-old male consulted at the emergency services for low abdominal pain. Physical examination disclosed a hypogastric mass. Patient evaluation by ultrasound, intravenous urography and pyelography revealed a right hydronephrotic ectopic kidney with lithiasis and pelvic localization. Nephrectomy via a right infraumbilical incision was performed.

CONCLUSION

Pelvic renal ectopy is uncommon, but not rare in our area. This anomaly is associated with a higher than normal incidence of hydronephrosis and lithiasis. The diagnostic techniques most frequently used to evaluate these patients are ultrasound, intravenous urography, cystography and pyelography. When a surgical procedure is performed, the anatomical features of this anomalous condition should be considered, such as abnormal vascularization, pyelourethral anomalies, kidney rotation and absence of perirenal fat tissue.
