The right sided syndrome, congenital absence of kidney and testis

Abstract EN

Unilateral renal agenesis (URA) is a developmental defect associated with anomalies of the genitourinary system.

The associations vary from absence of testis alone to high anorectal anomalies in other patients.

We present two interesting patients with URA, encountered recently.

Our first case was diagnosed with URA at the age of 11 years, which was detected on sonography, when he presented with pain abdomen.

The presence of an epididymal cyst masked the absence of ipsilateral testes leading to delay in the diagnosis.

Our second case was diagnosed with URA during the neonatal period when he presented with anorectal agenesis.

He underwent abdomino-anal pull-through operation and later clinical course was complicated by recurrent cystitis, secondary vesicoureteral reflux and hydroureteronephrosis of solitary kidney, progressing to chronic kidney disease.
