Nonobstructive urinary tract dilatation in children with diabetes insipidus

Congenital nephrogenic diabetes insipidus complicated with Hinman syndrome

“…1 Also, dilatation of the urinary tract or trabeculation of the bladder wall in NDI is not due to an obstruction of the urinary tract but is an adaptive change resulting from high urinary flow. 3 In addition to megacystis, megaureter, and hydronephrosis caused by persistent high urinary flow states in congenital NDI, voluntary retention of urine as a result of toilet training might have predisposed the present patient to severe dysfunctional voiding, including low detrusor contractility with significant residual urine and recurrent UTI. Managadze and Tchanturaia reported a strong relationship between bladder trabeculation and urinary retention.…”

“…On review of the literature, dilatation of the urinary tract was present in as much as 42–67% of the reported cases of NDI . Also, dilatation of the urinary tract or trabeculation of the bladder wall in NDI is not due to an obstruction of the urinary tract but is an adaptive change resulting from high urinary flow …”

Undiagnosed nephrogenic diabetes insipidus as a cause of acute urinary retention in a young soldier

“…It is a severe disease with manifestations in early infancy, including polyuria, polydipsia, hyposthenuria and hypernatraemic dehydration 3. Colliver et al 4 presented the cases of three young boys with NDI associated with rapid development of bladder hypertrophy and hydroureteronephrosis during childhood. They were all referred to their service with progressive renal tract dilatation, impaired renal function and incontinence.…”

Diabetes insípida nefrogénica

“…En algunos niños se ha observado que el alto flujo urinario induce el desarrollo de una vejiga trabeculada en ausencia de obstrucción infravesical; los estudios de urodinamia muestran una vejiga distendida con vaciamiento lento e incompleto, que agrava el deterioro de la función renal, por lo que se han requerido procedimientos como la cistostomía para asegurar el vaciamiento vesical 25 . Por otro lado, se ha informado de casos de pacientes con diabetes insípida nefrogénica que además presentan obstrucción del tracto urinario inferior (valvas uretrales inferiores).…”
