Some of the common malfunctions of the urinary tract are, urethral strictures, scars tissues developed after radiation therapy, surgery or procedures done on the urinary tract, urinary blockage, and urinary tract infections.
Learn about the investigations and the diagnosis
● UPJ obstruction can be treated with surgery. If condition is severe then it needs to be done early in life.
● For children open surgery is done while for adults a procedure known as pyeloplasty is done.
● In pyeloplasty a 2-3 inch cut is made just below the ribs and the obstructed segment of the ureter is removed.The normal caliber ureter is then attached to the renal pelvis.
● A stent (a tiny wire-meshed tube) is placed to drain urine from kidney. After the surgery heals, the stent is removed.
● The more common approach in adults is robotic assisted or laparoscopic pyeloplasty.
Recovery after surgery
● Patients will stay in the hospital for a day or two after surgery.
● The ureter may be swollen.The patient may have some pain for a few days after surgery.
● Kidney drainage may be poor at first, but gets better as the area heals.
● A few weeks after surgery, the stent is removed, and doctor may use an ultrasound to check for swollen kidneys.
Risks and complications
● Pyeloplasty has the best long-term success for patients who suffer from UPJ obstruction.
● After laparoscopic pyeloplasty, there could be scarring in the abdomen area.
● The future risks of this surgery could be kidney stones or kidney infections.
● Some patients are also at a risk of developing hypertension, infection, proteinuria or pregnancy related problems.
Follow-up after pyeloplasty
● Pyeloplasty is a procedure which has a good success rate and hence a repeat scan is not necessary for even five to seven years.
● In children, serial ultrasounds, measurement of resistive index(RI) using duplex ultrasonography and intravenous urography are done.
● In conclusion, most renal units remain stable after a successful pyeloplasty.
