Objective To compare the risk of postoperative ureteral stricture formation following retroperitoneal laparoscopic ureterolithotomy (RPLU) and ureteroscopy with holmium: YAG laser lithotripsy (URSL) in patients with proximal ureteral stones. Materials and Methods We retrospectively reviewed the medical records of patients who underwent RPLU or URSL for proximal ureteral stones between April 2011 and May 2015. Patients were allocated into URSL group or RPLU group and the outcomes were compared. Results A total of 201 patients who underwent 209 procedures including 159 URSL and 50 RPLU with a median follow-up of 30 months were included. No significant difference was observed among the two groups in most baseline parameters, while the stone size was significantly larger in the RPLU group (11.37 ± 2.97 vs 14.04 ± 4.38 mm, p = 0.000). Patients in RPLU group had markedly longer operative time (p = 0.000) and longer postoperative hospital stay (p = 0.000). The initial and one-month stone-free rates were significantly higher in the RPLU group (78.6% vs 100%, p = 0.000 and 82.4% vs 100%, p = 0.001, respectively). Patients in the RPLU had a higher complication rate (18.0% vs 9.4%, p = 0.098) and lower ureteral stricture rate (2.5% vs 2.0%, p = 1.000), while the difference was not significant. Further logistic regression model identified RPLU and female sex as independent risk factors for postoperative complication (Odds Ratio[OR] = 3.57, p = 0.035 and OR = 3.57, p = 0.025, respectively); however, URSL was not an independent risk factor for the formation of postoperative ureteral stricture after adjusting confounding variables (OR = 0.90, p = 0.935). Conclusion RPLU and URSL have similar postoperative ureteral stricture formation risks. RPLU can provide significantly higher stone clearance rate, but relates with more postoperative complications.

Objectives: Holmium: YAG laser has gained its popularity throughout the years and is used to treat sialolithiasis, which helps to overcome the limitations of traditional sialendoscopic lithotripsy for larger-sized salivary stones. However, little information is available regarding factors predicting the success rate of Holmium: YAG laser intraductal lithotripsy. The purpose of this study is to investigate the factors affecting the success rates of Holmium: YAG laser lithotripsy for salivary stones treatment in a tertiary care hospital. Methods: A retrospective study conducted in patients receiving sialolithiasis surgery under sialendoscopy from May 2013 to March 2015 at Mackay Memorial Hospital, Taiwan. Data on various factors, including patients’ age, gender, glands, size of largest stone, multiple stones (≥2 stones), location of the stone (distal duct, middle duct, proximal duct, and hilum), and operative time. The success of the surgery defined as patients without any complaints such as swelling or tenderness. Logistic regression and Fisher exact tests were employed to examine these factors on the success rate. Results: Fifty-four patients who received sialendoscopy surgery with a mean age of 35.74 years old recruited. Logistic regression identified the operation time exceeding 210 minutes showed 23.497 folds higher odd ratio of having a result of operation failure ( P < .05). Conclusion: The prolonged operation time is the sole independent factor affecting the successful outcome for salivary gland intraductal laser lithotripsy. We recommend operative time be no more than 210 minutes to increase the success rate in salivary gland Holmium: YAG laser intraductal lithotripsy.

Now lithoclast has become more popular tool than various intracorporeal lithotripters for the treatment of ureteric stones. Recently the Holmium:YAG laser has been used with a wide range of potential urological applications, including intracorporeal lithotripsy of ureteric stones. This study was conducted to compare the use of Forceps and Dormia basket in the management of ureteric stone between Holmium: YAG Laser and Pneumatic Lithotripsy. It was a longitudinal follow-up comparative study conducted at Combined Military Hospital, Dhaka. All the respondents were admitted patients in Combined Military Hospital Dhaka, under Urology Ward. A total of 100 patients were enrolled for this study under convenient purposive sampling method. They all were admitted with the complaints of upper ureteric stone who underwent ureteroscopic lithotripsy from October 2010 to September 2012. In 50 patients, Laser Lithotripsy (LL) was used and in other 50 patients Pneumatic Lithotripsy (PL) was used. Same ureteroscope, video monitor, baskets and irrigation devices were used in both the samples. Patients were followed up after 1st and 3rd months interval. Lithotripsy follow-up was done with radiograph and ultrasonography of kidney, ureter and bladder.  Patients with migrated fragments or incomplete clearance were underwent an auxiliary procedure such as shock wave lithotripsy. Mean stone size was 1.36 ± 0.36 cm in group Laser lithotripsy (LL) and 1.37± 0.36 cm in group Pneumatic lithotripsy (PL). The immediate stone clearance rate was significantly higher in Group LL (94.0%) than Group PL (76.0%). Proximal migration of fragments were 6.0% in LL group and 24.0% in PL group. Use of stone retrieval equipment (baskets, forceps) was 16.0% and 64.0% in LL and PL group respectively (p<0.05). On the other hand stone fragments clearance requiring auxiliary procedures were 6% and 24% in LL and PL group respectively. The mean lithotripsy time was 40.46 ± 19.25 min and 36.86 ± 14.83 min the LL and PL group respectively. Use of stone retrieval equipment(baskets, forceps) was significantly lower in Holmium: YAG assisted ureteroscopy than pneumatic lithotripsy group. Bangladesh Med J. 2019 Jan; 48 (1): 26-30
