Patient's question:
Detailed medical condition and consultation purpose: Congenital ureteropelvic junction stenosis.Current general condition: Backache in the morning.
History of diagnosis and treatment, as well as effectiveness: Undergone renal pelvis imaging, renal blood flow study, and retrograde imaging. No stones detected.
Doctor's answer:
Hello: Any narrowing or obstruction of the urinary tract, as well as normal dysfunction of the neuromuscular system, can impede urine flow, causing urinary obstruction. Due to poor urine drainage in the upper parts of the obstruction, pressure gradually increases, leading to dilatation of the tubes. Ultimately, this results in kidney hydronephrosis, expansion, thinning of the renal parenchyma, and reduced renal function. If bilateral obstruction occurs, it can lead to severe consequences such as uremia.Therefore, in terms of treatment, the first priority is to actively treat the underlying cause. This means actively treating the ureteral obstruction and, if necessary, considering surgical intervention.
