TO EVALUATE EFFICACY OF LAPAROSCOPIC TRANSPERITONEAL PYELOLITHOTOMY FOR MANAGEMENT OF RENAL PELVIC STONES IN TERM OF BLOOD LOSS

Background: To evaluate efficacy of laparoscopic transperitoneal pyelolithotomy for management of renal pelvic stones in term of blood loss Methods: This study has been conducted in the Department of General surgery, Indira Gandhi Medical College, Shimla on selected patients of Renal pelvis stones admitted in institution Results: Mean blood loss in successful laparoscopic surgery was 58.33 ml and in lap converted to open was 200 ml. Conclusion: Laparoscopic pyelolithotomy is a feasible and safe operation for patients with renal stones in centers with adequate experience in laparoscopy and well trained surgeons. It is found to be safe, effective and efficient with proper patient selection and adherence to standard laparoscopic surgical principles.

Comparison between different techniques for management of renal stones in horseshoe kidneys

Objective To report the operative management , intra and post operative complications and subsequent stone-free rates of patients with urolithiasis in a horseshoe kidneys. Materials and Methods We retrospectively reviewed all patients presenting to our centre with a horseshoe kidney and urolithiasis over a 20-year period. The stone burden, surgical management, complications and stone clearance rates were recorded. Results In all, 80 patients with urolithiasis in horseshoe kidney were treated. Percutaneous nephrolithotomy (PCNL) was used in 28 patients. 12 patients had laparoscopic assisted PCNL , 8 had flexible ureteroscopy and 18 had laparoscopic pyelolithotomy . PCNL was used for large stones = (mean digitized surface area= 614.32 mm 2 ) and required one to four stages to achieve an overall stone clearance rate of 88%. Stones were cleared at one sitting in 77% of PCNL procedures. only 33% of patients treated with flexible ureteroscopy was cleared from stones in one session and surprisingly, 89% of patients treated with laparoscopic pyelolithotomy was stone free after one session Complications were minimal, with 15% minor and 3% major complications in the PCNL group only.. Conclusions Appropriate management of urolithiasis within the horseshoe kidney depends not only on stone burden, but also on stone location, calyceal configuration and malrotation. Stones can be cleared successfully in almost all patients providing that all techniques are available to the operating surgeon.

Laparoscopic Pyelolithotomy for Recurrent Stone in Previously Operated Ectopic Pelvic Kidney

An ectopic kidney is a rare congenital anomaly that has been associated with complications as reflux, hydronephrosis, nephrolithiasis, and sometimes renal failure. Calculous diseases in the pelvic kidney due to their anatomical characteristics pose a significant challenge to the surgeon. We herein report a case of transperitoneal laparoscopic pyelolithotomy for treatment of renal pelvis stone in an ectopic pelvic kidney who had already undergone open pyelolithotomy in past. A 34 years old man presented to our hospital with pain abdomen for five months and a history of left open pyelolithotomy done almost eleven years back. Computed tomography scan revealed severe hydronephrosis and 3.5 cm calculus in the pelvis of ectopic malrotated left kidney. The patient underwent left laparoscopic pyelolithotomy, complete stone clearance was achieved, 20 fr drain was placed with no DJ (Double J) stent. For two consecutive days there was significant drain output, subsequently cystoscopy with DJ stenting was done then drain output was reduced. On fifth postoperative day the drain was removed and he was discharged. In a patient with a malrotated pelvic kidney with recurrent stone and past surgery, proper pre-operative evaluation & the selection of the most appropriate surgical technique play a crucial role to get the best surgical outcome.

Efficacy and safety of laparoscopic pyelolithotomy versus percutaneous nephrolithotomy for treatment of large renal stones: a meta-analysis

Background We aimed to compare the efficacy and safety of laparoscopic pyelolithotomy (LPL) versus percutaneous nephrolithotomy (PCNL) for treating renal stones larger than 2 cm. Methods We searched the PubMed, Embase, Web of Science, SinoMed, and Chinese National Knowledge Infrastructure databases for studies that compared the surgical outcomes of LPL and PCNL. We conducted a meta-analysis of the retrieved studies, expressed as weighted mean difference or risk ratios with 95% confidence intervals. Results We included 25 studies (1831 patients). LPL was associated with a significantly higher stone-free rate, lower rates of blood loss, complementary treatment, blood transfusion, and complications, and less reduction in hemoglobin level compared with PCNL. LPL and PCNL were similar in terms of duration of hospital stay, conversion rate, changes in glomerular filtration rate and creatinine level, and mean time of postoperative analgesia. However, LPL was associated with a longer operation time than PCNL. Conclusion LPL appears to be more effective and safer than PCNL in patients with large renal stones, by increasing the stone-free rate and reducing blood loss, complementary treatment, blood transfusion, and complications compared with PCNL. LPL may thus be a useful modality for treating patients with large renal stones.
