Engorged kidneys in pregnancy call for relieving nephrostomy, if locally delimited or systemic effects threaten to be a risk to mother and/or child. Five women were treated over the past five years, with percutaneous nephrostomy being performed on them for acute pyelonephritis gravidarum (n = 4, among them two with one kidney) or asymptomatic collateral excessive ectasia of the pyelo-calyceal system (n = 1). The intervention was followed by antegrade splinting in two cases. Soon clinical but less sonographic improvement was recordable from four patients as a result of renal relief. Delivery was necessary in one case, six days after nephrostomy. Widening application of nephrosonography also in pregnancy should not become a temptation for percutaneous nephrostomy to be performed also on cases of symptomatic urinary stasis. A more generous approach should be taken only to functionally or anatomically solitary-kidney cases.
