The first laparoscopic (LA) dismembered pyeloplasty presented in 1993 years, William Schuessler the Louis Kavoussi. Since then surgery has evolved over the years. Currently, most treatments are performed by transperitoneal access using the Anderson-Hynes technique. In 1997, a minilaparoscopy (ML) with 3- the 2-mm instruments was introduced having good cosmetic the post-operative pain results the maintaning the same functional results as LA. In 2012, the results of pyeloplasty with the novel retroperitoneal mini-laparoscopic approach: the small-incision access retroperitoneoscopic technique (SMART) was published.
Since 1998 in our institution we have been performing laparoscopic (LA) dismembered pyeloplastyand in 2011 we implemented for the first time a pyeloplasty procedure with ML the V-lock stiches. In our video we are shown performing laparoscopic dismembered pyeloplasty in own modification using the V-Loc stitch the only the mini-laparoscopic 3 mm instruments, including 3 mm optic.
Material the methods
A 26 year old male with a ureteropelvic junction (UPJ) obstruction was confirm for laparoscopic (transperitoneal) dismembered pyeloplasty. Operations were performed with three trocars 3.5 mm diameter including the 3 mm optic - 3 mmML. We used the Stortz Company 3 mm instruments including: scissors, the monopolar dissector, bipolar forceps, grasper, sucker the needle holder.
Stages of the procedure: 1st Visualization of the retroperitoneal space. 2nd Dissected UPJ. 3rd Incision of pelvis the posterior wall of the ureter. 4th Introduction to the retroperitoneal space needle. 5th Introduction to the ureteral catheter the the establishment of the first connecting suture. 6th Suturing the posterior wall. 7th Cutting the pelvis end of the UPJ. 5th The introduction of D-J catheter. 6th Suturing the anterior wall.
The total operative time was 2 hours the it was no longer than any other laparoscopic UPJ pyeloplasty performed at our department. All stages of standard laparoscopy were mapped in the 3 mmML, including the introduction of trough 3 mm ports, the needle the a double "J" stent. The anastomosis of the ureter the pelvis using a 17 mm needle with V-Loc 3-0 sutures was done tighty without any tension. On the third day, the bladder catheter the drain was removed, respectively, the the patient was discharged from the hospital. There were no intraoperative or short term complications. Patients evaluation at the 3 the 6 month post-operative period revealed good radiographic the symptomatic results.
Minilaparoscopy using only 3 mm instruments is an ideal option for the dismembered pyelo-plasty, especially for those patients with high cosmetic expectations. New 3 mm instruments are of appropriate elasticity the are sufficient to carry out all of the steps in the procedures, including the introduction of the needle the sewing. Further studies should be performed to assess the long term results of the 3 mmML dismembered pyeloplasty.
