laparoscopic pyeloplasty with concomitant Pyelolithotomy
The Journal of Urology, 2002Co-Authors: Sanjay Ramakumar, Vanessa Lancini, David Y. Chan, Louis R. Kavoussi, Kellogg J Parsons, Thomas W. JarrettAbstract:Purpose: We present our experience with laparoscopic pyeloplasty plus Pyelolithotomy in patients in whom stones were not the cause of ureteropelvic junction obstruction.Materials and Methods: A transperitoneal approach was used for laparoscopic pyeloplasty and Pyelolithotomy in 19 patients (20 renal units). Before ureteropelvic junction repair stones were extracted through a small pyelotomy that was eventually incorporated into the final pyeloplasty incision. Stones in the renal pelvis were removed with rigid graspers under direct laparoscopic vision. A flexible cystoscope introduced through a port was used to extract stones in the calices. The renal pelvis was reconstructed based on the anatomy of the ureteropelvic junction.Results: A median of 1 stone (range 1 to 28) was recovered. In 11, 8 and 1 patients the Anderson-Hynes dismembered pyeloplasty, Y-V plasty and the Heinecke Mickulicz procedure were performed, respectively. At 3 months 2 patients had residual calculi for a procedural stone-free rate of...

LAPAROSCOPIC PYELOPLASTY WITH CONCOMITANT Pyelolithotomy

At 3 months 2 patients had residual calculi for a procedural stone-free rate of 90%. There was no evidence of obstruction in 18 of the 20 cases (90%), as confirmed by negative diuretic scan or radiological improvement of hydronephrosis. At a mean followup of 12 months (range 3 to 57) 2 additional patients had recurrent stones for an overall long-term stone-free rate of 80% (16 of 20). Laparoscopic Pyelolithotomy is feasible when combined with pyeloplasty. Our results are comparable to those of stone removal during open pyeloplasty or percutaneous endopyelotomy. The advantages of open surgery appear to be maintained in this minimally invasive approach.

combined laparoscopic Pyelolithotomy and endoscopic pyelolithotripsy for staghorn calculi long term follow up results from a case series
Therapeutic Advances in Urology, 2016Co-Authors: Antonio Luigi Pastore, Giovanni Palleschi, Luigi Silvestri, Antonino Leto, Andrea Ripoli, Andrea Fuschi, Yazan Al Salhi, Domenico Autieri, Vincenzo Petrozza, Antonio CarboneAbstract:Purpose:Staghorn renal stones are a challenging field in urology. Due to their high recurrence rates, particularly those associated with an infective process, a complete removal is the ultimate goal in their management. We report our experience with a combined approach of laparoscopic Pyelolithotomy and endoscopic pyelolithotripsy, the stone clearance rate, and long-term, follow-up outcomes.Methods:From June 2012 to October 2014, nine adult patients with large staghorn renal calculi (mean size, 7.2 cm; range, 6.2–9.0 cm) underwent a combined laparoscopic and endoscopic approach. The technique comprised laparoscopic Pyelolithotomy and holmium-YAG laser stone fragmentation with the use of a flexible cystoscope introduced through a 12 mm trocar.Results:The average operative time was 140 min (range, 90–190 min). The mean estimated hemoglobin loss was 0.6 mmol/l (range 0.5–0.7 mmol/l). None of the patients required an open- surgery conversion. The mean hospital stay was 4 days (range, 2–6 days).

Combined laparoscopic Pyelolithotomy and endoscopic pyelolithotripsy for staghorn calculi: long-term follow-up results from a case series
SAGE Publishing, 2016Co-Authors: Antonio Luigi Pastore, Giovanni Palleschi, Luigi Silvestri, Antonino Leto, Andrea Ripoli, Andrea Fuschi, Yazan Al Salhi, Domenico Autieri, Vincenzo Petrozza, Antonio CarboneAbstract:Purpose: Staghorn renal stones are a challenging field in urology.

None of the patients required an open- surgery conversion. The mean hospital stay was 4 days (range, 2–6 days). A computed tomography urogram control at 6 months of follow up did not show any stone recurrence. Conclusions: Laparoscopic Pyelolithotomy combined with endoscopic pyelolithotripsy could be a therapeutic option in cases where mini-invasive procedures, that is, extracorporeal shock wave lithotripsy, ureteroscopic lithotripsy, and percutaneous nephrolithotomy (PCNL) have failed. This technique has a high stone-clearance rate (75–100%) comparable with open surgery and PCNL. However, it could be technically demanding and should be performed by skilled laparoscopy surgeons

Nephrolithotomy Performed Concurrently With Laparoendoscopic Single-site Pyeloplasty
Urology, 2013Co-Authors: Yasuyuki Naitoh, Akihiro Kawauchi, Fumiya Hongo, Koji Okihara, Kazumi Kamoi, Tsuneharu MikiAbstract:Introduction The objective of the present study was to evaluate the results of laparoendoscopic single-site (LESS) pyeloplasty and Pyelolithotomy, which were performed concurrently in patients with pelviureteric junction obstruction (PUJO) and renal stones. Technical Considerations Four patients with PUJO and renal stones underwent Pyelolithotomy performed concurrently with LESS pyeloplasty. In 3 patients, a 2.5-cm incision was made in the umbilical region. In the fourth patient, the 2.5-cm vertical incision was made at a site 7 cm below the umbilical region because of a stone in the right lower calyx. After dissection of the pelviureteric junction, an incision of approximately 1 cm was made along the presumed transection line of the renal pelvis. The Pyelolithotomy was performed using a 24F rigid nephroscope through a SILS port. Dismembered pyeloplasty was performed after extraction of the renal stones was completed. The mean operation time was 277 minutes (range, 225-373), and the mean lithotomy time was 31 minutes (range, 20-50). No intraoperative or postoperative complications were observed. For all 4 patients, discharge from the hospital was possible after a mean of 3.4 postoperative days (range, 3-4). All patients became stone free. Postoperative ultrasound revealed that hydronephrosis improved in all patients. In all patients, resolution of the symptoms was confirmed. Conclusion LESS nephrolithotomy with pyeloplasty is a safe and effective procedure with a good cosmetic result for patients with PUJO and renal stones.

Robot-Assisted Laparoscopic Extended Pyelolithotomy and Ureterolithotomy
Atlas of Robotic Urologic Surgery, 2017Co-Authors: Jessica N. Lange, Mani Menon, Ashok K. HemalAbstract:This chapter provides an overview of the latest robotic approaches to stone-removing surgery. These include transperitoneal Pyelolithotomy, retroperitoneal Pyelolithotomy, ureterolithotomy, and anatrophic nephrolithotomy. We provide diagrams to assist with optimal port placement for all versions of the da Vinci robot platform. Finally, we provide suggestions as to when the robotic approach to stone-removing surgery may be preferred.

Current role of robot-assisted Pyelolithotomy for the management of large renal calculi: a contemporary analysis.
Journal of endourology, 2009Co-Authors: Gina M. Badalato, Mani Menon, Ashok K. Hemal, Ketan K. BadaniAbstract:Abstract Background and Purpose: The scope of robot-assisted surgery continues to expand with the application of these systems to management of large upper-tract urinary stones, with or without concomitant pyeloplasty. The known advantages of the robot-assisted approach, including enhanced optics, dexterity, wristed instrumentation, and ergonomics, can facilitate complex reconstruction of the collecting system, including uteropelvic junction repair. With the favorable outcomes of contemporary robot-assisted pyeloplasty series, robot-assisted applications have been translated to Pyelolithotomy with or without concomitant upper-tract reconstruction. The early results of robot-assisted lithotomy reveal the procedure is a safe and efficacious approach for patients with large renal stones; nevertheless, the technique has met limited success in cases of large staghorn calculi. Our purpose was to evaluate the current role of robot-assisted Pyelolithotomy for the management of large renal calculi. Conclusion: Giv...

Pure robotic extended Pyelolithotomy: cosmetic replica of open surgery
Journal of robotic surgery, 2007Co-Authors: Rishi Nayyar, Pankaj Wadhwa, Ashok K. HemalAbstract:Percutaneous nephrolithotomy (PCNL) has replaced open Pyelolithotomy as the procedure of choice for treating large-burden renal stone disease, especially staghorn calculi. Although it is a minimally invasive procedure, it involves transgressing the renal parenchyma and is thus associated with its unique set of complications. The evolution of laparoscopic Pyelolithotomy and robotic assistance has provided an opportunity to the surgeon to revisit Pyelolithotomy in a minimally invasive manner following the age-old principles of the era of open renal surgery. We report the feasibility and our experience with this technique in three cases of partial staghorn calculus with intra-renal pelvis.
