Nephrological and urological symptoms in patients with Robinow syndrome - a report of two cases.

UNLABELLED: Robinow syndrome is a rare congenital syndrome described in 1969 by Meinhard Robinow. The genetic background is heterogeneous - mutations of DVLI1, DVLI3, WNT5A genes (mild, autosomal dominant inheritance) or ROR2 gene (severe, autosomal recessive inheritance) are responsible for the syndrome. The syndrome is characterized by facial dysmorphism, skeletal defects, short stature, cardiovascular and urinary system abnormalities.

CASE REPORT: We report nephrological and urological problems in two 4-year-old male patients with Robinow syndrome. The first patient has a horseshoe kidney located mainly on the right side, right vesicoureteral reflux grade II, dysfunctional voiding, buried penis, and retractile testicles. The second patient has recurrent urinary tract infections; diagnostic findings include left kidney duplication, grade II left vesicoureteral reflux, large posterior urethral diverticulum, dysfunctional voiding, buried penis, glanular hypospadias, and bilateral cryptorchidism.

CONCLUSIONS

Patients with Robinow syndrome require multidisciplinary care, including nephrology-urology care. Nephrological and urological manifestations in children with Robinow syndrome are diverse, and urinary tract defects may be atypical and complex.
