Ureteropelvic junction obstruction or Pelvi-ureteric junction obstruction (UPJO/PUJO)

UPJO or PUJO is a condition where the junction between the part of the kidney that collects urine (renal pelvis) and the ureter is narrow, urine thus does not drain easily causing dilatation of the collecting system caller as hydronephrosis. PUJ obstruction is usually congenital but can be acquired as well. Let's talk about the causes of UPJO- 1)● an aperistaltic segment of the ureter due to abnormal arrangement of the smooth muscle layer, which in turn will impair the urine drainage from the renal pelvis into the ureter and causes functional obstruction rather than mechanical. 2)● High insertion of the ureter into the renal pelvis 3)● Entrapment of the ureter by a crossing accessory renal vessel. Acquired causes can be like retroperitoneal mass or lymphnodes, stones, radiation, tumors, etc. #Urology #UPJO #PUJO #Ureteropelvicjunction #Pyeloplasty #LaparoscopicPyeloplasty #urologist_noida #urologist #DrPrashantKumar
