Pyeloplasty is a highly effective surgical procedure designed to correct the blockage or narrowing in the ureteropelvic junction, ensuring proper urine flow from the kidney to the bladder. To perform this procedure, the patient should have access to cutting-edge medical facilities and highly skilled surgeons such as Dr. Shirin Razdan, who specializes in minimally invasive and robotic-assisted pyeloplasty. If you are seeking an expert urologist who has expertise in the pyeloplasty treatment procedure, then Dr. Shirin Razdan is here to assist you!
In Miami, there are several leading urology centers and surgeons who offer state-of-the-art treatments for kidney-related conditions. One of the highly effective treatment procedures is Pyeloplasty, which helps to restore normal kidney function. If you live in Miami and are seeking expert care, Dr. Shirin Razdan can assist you with top-tier medical care and treatment procedures, including pyeloplasty.
This is a minimally invasive procedure that, when performed by Dr. Razdan, can help cure kidney blockage occurring at the UPJ-uureteropelvic junction (the point where the kidney joins the ureter). The UPJ can get narrow or blocked due to several reasons, including poor urinary drainage, pain, and the deterioration of kidney function.
Dr. Shirin Razdan has successfully performed a large number of robotic UPJ repairs on patients who failed pyeloplasties in the past.
Ureteropelvic Junction (UPJ) is a condition characterized by a blockage of urine outflow from the kidney. The condition may result from congenital scarring or pressing a blood vessel on the ureter. UPJ is painful and may cause issues such as infection, kidney stones, and even loss of kidney function.
Pyeloplasty is a surgical procedure involving the removal of the UPJ obstruction. Dr. Razdan aims to restore the normal functioning of the urine outflow. Traditionally, the procedure was performed as an open surgery by making an 8–12-inch incision in the flank. Today, the surgery is performed in a minimally invasive way, known as robotic pyeloplasty, a minimally invasive alternative procedure with success equal to that of traditional open surgery. The best part is that this procedure comes with many additional benefits, including:
Pyeloplasty is typically performed to treat a condition known as ureteropelvic junction (UPJ) obstruction, where the connection between the kidney and the bladder is blocked, causing urine backup, which potentially damages the kidney.
Untreated UPJ obstruction can lead to progressive kidney damage, recurrent infections, pain, and loss of renal function. Pyeloplasty offers a durable solution that restores normal urine flow, protects kidney function, and relieves symptoms for most patients.
Pyeloplasty — when performed by experienced surgeons — has excellent outcomes:
If an initial pyeloplasty fails, redo pyeloplasty also has good outcomes (often >85–90%), significantly better than less definitive procedures like endopyelotomy.
| Approach | How It Works | Typical Success | Pros / Cons |
| Open Pyeloplasty | Traditional surgery through a larger incision | ~90–100% | Gold standard with excellent outcomes; longer recovery |
| Laparoscopic Pyeloplasty | Minimally invasive keyhole surgery | ~90–95% | Less pain, quicker recovery; requires advanced skills |
| Robot-Assisted Pyeloplasty | Robotic keyhole surgery with enhanced precision | ~95–98% | Excellent precision, shorter hospital stay, faster recovery |

The pyeloplasty procedure performed by Dr. Shirin Razdan comprises the following steps:
Step 1: The procedure starts with the patient being put into a deep sleep under general anesthesia (this helps the patient to avoid any pain or discomfort throughout the procedure).
Step 2: Dr. Razdan will make one or more tiny incisions in the patient’s stomach area on the side of the affected kidney.
Step 3: The narrowed or blocked part of the ureter will be removed surgically.
Step 4: The ureter is attached again to the renal pelvis of the kidney.
In most cases, Dr. Razdan places a stent (small tube) inside or outside the section where surgery is done. Of course, a catheter is placed on the other side of the stent to collect urine. This is only temporary until the kidney heals and begins to function properly.
Step 5: Finally, the incision is closed by a suture.

Answer. The pyeloplasty is needed when the tube that drains urine from the kidney and into the bladder is blocked.
Answer. Some Major benefits of pyeloplasty include smaller incisions, less pain, reduced blood loss, shorter hospital stays, and faster recovery times.
Answer. Yes, pyeloplasty can often lead to improved kidney function in cases of ureteropelvic junction obstruction by relieving the blockage and allowing the kidney to function more effectively.
Answer. It can take 3 to 4 weeks to completely recover from a pyeloplasty treatment.
Answer. Pyeloplasty treats ureteropelvic junction obstruction (UPJO) — a blockage at the point where the kidney meets the ureter.
Answer. Success rates are high — generally 90–98% when performed by experienced surgeons.
Answer. Yes — it restores normal urine drainage and can stabilize or improve kidney function over time.
Answer. Discomfort is expected after any surgery, but minimally invasive techniques generally result in less postoperative pain.
Answer. Most pyeloplasties take several hours, depending on complexity and technique.
Answer. Risks include bleeding, infection, recurrence of obstruction, urinary leak, or need for additional procedures — but complication rates are low with experienced surgeons.
