Official Description

Laparoscopy, surgical; ureteroneocystostomy with cystoscopy and ureteral stent placement

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Laparoscopy, surgical ureteroneocystostomy with cystoscopy and ureteral stent placement is a minimally invasive surgical procedure that involves the re-implantation of the ureter into the bladder. This technique is performed using a laparoscopic approach, which allows for smaller incisions and reduced recovery time compared to traditional open surgery. The procedure begins with the creation of a small incision below the umbilicus, through which a trocar is inserted to access the peritoneal cavity. A laparoscope is then introduced to provide visualization of the internal structures. The abdomen is insufflated to create a working space for the surgeon. Additional incisions are made to allow the introduction of surgical instruments necessary for the procedure. During the surgery, the ureter is carefully mobilized, starting from the area proximal to the broad ligament down to the ureterovesical junction. An incision is made in the bladder's muscular wall, known as the detrusor muscle, to form a trough at the site where the ureter will be reattached. The ureter is then inserted into this trough, and the edges of the detrusor muscle are sutured around the ureter to secure it in place. Following the ureteroneocystostomy, cystoscopy is performed, which involves inserting a cystoscope through the urethra into the bladder to visualize the ureteral opening. A guidewire is advanced into the ureter, and a ureteral stent is placed over the guidewire to ensure proper drainage and support of the ureter during the healing process. The procedure concludes with the placement of a urethral catheter, removal of the cystoscope and laparoscope, and closure of the abdominal incisions.

1. Indications

The procedure of laparoscopic ureteroneocystostomy with cystoscopy and ureteral stent placement is indicated for various conditions affecting the ureter and bladder. These may include:

  • Ureteral Obstruction - A blockage in the ureter that prevents urine from flowing from the kidney to the bladder.
  • Vesicoureteral Reflux - A condition where urine flows backward from the bladder into the ureters, which can lead to urinary tract infections and kidney damage.
  • Ureteral Injury - Damage to the ureter that may occur due to trauma, surgical complications, or other medical conditions.
  • Congenital Anomalies - Birth defects affecting the ureter or bladder that may require surgical correction.

2. Procedure

The laparoscopic ureteroneocystostomy procedure involves several key steps, each critical to the successful re-implantation of the ureter into the bladder:

  • Step 1: Accessing the Peritoneal Cavity - The procedure begins with the creation of a small incision inferior to the umbilicus. A trocar is inserted through this incision to access the peritoneal cavity, allowing for the introduction of a laparoscope. The abdomen is then insufflated to create a working space for the surgical instruments.
  • Step 2: Mobilizing the Ureter - Additional portal incisions are made to facilitate the introduction of surgical instruments. Under laparoscopic control, dissection is performed to mobilize the ureter, starting from the area proximal to the broad ligament and extending down to the ureterovesical junction.
  • Step 3: Creating the Detrusor Trough - An incision is made in the muscular wall of the bladder, specifically in the detrusor muscle, to create a trough at the planned site for the ureteral transplant. This trough is located along the lateral aspect of the bladder.
  • Step 4: Inserting the Ureter - The ureter is inserted into the detrusor trough created in the previous step. The ureter is then anastomosed to the edges of the detrusor muscle, ensuring a secure connection.
  • Step 5: Cystoscopy and Stent Placement - Following the ureteroneocystostomy, a cystoscope is inserted through the urethra into the urinary bladder to identify the opening in the ureter. A guidewire is advanced into the ureter, and a ureteral stent is placed over the guidewire under laparoscopic visualization to facilitate urine drainage.
  • Step 6: Completing the Procedure - After the stent placement, a urethral catheter is inserted to assist with urine drainage. The cystoscope and laparoscope are then removed, and the abdominal incisions are closed to complete the procedure.

3. Post-Procedure

After the laparoscopic ureteroneocystostomy with cystoscopy and ureteral stent placement, patients typically require monitoring for any complications. Post-procedure care may include managing pain, monitoring for signs of infection, and ensuring proper urine output. The urethral catheter may remain in place for a period to facilitate healing and drainage. Patients are usually advised on activity restrictions and follow-up appointments to assess the success of the procedure and the condition of the ureteral stent. It is important to monitor for any potential complications such as urinary leakage or obstruction, which may necessitate further intervention.

LT Left side (used to identify procedures performed on the left side of the body)
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
