pyeloplastyhave

There is no widely recognized medical term "pyeloplastyhave." The phrase may be a typographical error or a misconstructed word. This article provides information on pyeloplasty, a surgical repair of the ureteropelvic junction.

Pyeloplasty is used to treat ureteropelvic junction obstruction (UPJO), a condition that can cause hydronephrosis and impaired drainage from the kidney to the ureter. It may be congenital or acquired and can present with flank pain, urinary tract infections, stones, or reduced kidney function. The goal is to remove or bypass the obstruction and create a wide, unobstructed connection between the renal pelvis and the ureter.

Surgical approaches include open pyeloplasty and minimally invasive techniques such as laparoscopic and robot-assisted laparoscopic pyeloplasty. Endopyelotomy, an endoscopic incision through the UPJ, is an option in selected cases but generally has lower long-term success rates than open or minimally invasive approaches. Success rates for properly selected patients typically range from about 85% to 95% with contemporary techniques.

Procedure overview: under anesthesia, the surgeon exposes the UPJ, resects or incises the narrowed segment, and creates a tension-free anastomosis between the renal pelvis and the ureter. A ureteral stent is usually placed to aid drainage during healing. Minimally invasive approaches often result in shorter hospital stays and faster recovery compared with open surgery, though individual experience and anatomy influence outcomes.

Follow-up includes imaging studies such as ultrasound or diuretic renography to assess drainage and kidney function. Potential complications include infection, urine leakage, stent-related symptoms, bleeding, or recurrence of obstruction requiring further treatment. Pyeloplasty has a long history, with early reports by Anderson and Hynes and ongoing refinements through robotic and minimally invasive techniques.
