Abstract Objective The aim of this study was to compare the efficacy & safety of holmium laser and pneumatic lithotripsy used in the ureteroscopic treatment of ureteral stones. Materials and Methods A prospective randomized clinical study was done using the data of patients to whom ureteroscopic lithotripsy (URL) was applied for ureter stones in our clinic. Then these patients were separated into 2 groups according to the type of lithotriptor used in stone fragmentation as laser lithotripsy (Group 1) and pneumatic lithotripsy (Group 2). Results Statistically, the two groups were similar in respect of the number of stones, stone burden and the number of double J stents applied intra-operatively. Mean operating time was calculated as 62.9 (±7.69) minutes in Group 1 and 50.98 (±6.63) minutes in Group 2. The mean operating time was found to be higher in group 1 than group 2 (P = 0.000). On postoperative day 1 after the URL, the SFR of Group 1 79.0% found to be significantly high compared to the SFR of Group 2 (64.0%) (P = 0.019), while at postoperative month 1, the SFR of both groups (Group 1 84%, Group 2 80%) was found to be similar (P = 0.462). Conclusions Compared to the pneumatic lithotripter, the Ho: YAG laser seems to have a statistically significant higher SFR in the early postoperative period (1 day), even though there are statistically insignificant success rate (after 1 month) and complications (hematuria, mucosa injury, stone migration, stricture and perforation avulsion).

Aim of the study: To demonstrate how, in a center with a large number of patients, as our center is, it is possible to perform ureterolithotripsy using a limited set of instruments. Methods: We evaluated medical charts of our center related to semirigid ureteral ureteroscopy (URS) with ureterolithotripsy using Holmium laser performed from July 2004 to July 2011. Overall, 658 URS for ureteral stones were performed in 601 patients, of which 204 in proximal ureter (31%), 86 in the mid (13.06%) and 368 (57.76%) in the distal ureter. In 504 patients (76.5%) ureterohydronephrosis (Grade II-III) was observed. In 57 patients (8.6%), we performed a bilateral approach at the same time, but most patients had a solitary distal ureteral stone. 106 patients (16.1%) had more than one stone in their distal ureter and 96 (14.8%) had a proximal ureteral stone treated in the same surgery as well. Results: The overall stone-free rate for ureteral stones was 86.1% (567/658). Success rates for proximal, medial and distal ureteral stones were 68.13% (139/204 patients), 84.8% (73/86 patients) and 96.4% (355/368 patients), respectively. One hundred and twenty patients (18.3%) required additional surgical treatment for their stones beyond the initial URS, including a second URS in 97 patients (14.74%) and URS plus Retrograde Intra-Renal Surgery (RIRS) in 23 patients (3.54%). The overall stonefree rate after the second treatment was 99.3%. Intra-operative complications accounted for 5.92% and consisted of ureteral perforations in 16 pts (2.4%), erosions of urothelium leading to significant bleeding in 15 pts (2.27%), severe pain in 4 pts (0.6%), fever in 3 pts (0.45%) and one case of ureteral avulsion (0.15%). Conclusions: This study demonstrates that the use of Holmium laser lithotripsy is a safe and effective means of treating ureteral stones regardless of sex, age, stone location, or stone size. The instrumentation we used was extremely limited, in order to reduce costs related to the procedure to an absolute minimum whilst maintaining the two quality indicators for the procedure, namely success rate and length of hospitalisation (86.1% and 34 hours).

Percutaneous Nephrolithotripsy

The use of intracorporeal lithotripsy for the management of larger ureteral and intrarenal calculi has dramatically improved. Although the choice of intracorporeal fragmentation is frequently based on the location and composition of the stone to be treated, the experience of the clinician and availability of equipment often dictates this decision. Several different modalities of intracorporeal lithotripsy are currently available. Ultrasonic lithotripsy is mainly used for the fragmentation of large renal calculi during percutaneous nephrolithotripsy procedures. Ultrasound is used rarely via an ureteroscopic approach. Significant advances in laser fibres and power generation systems have propelled laser lithotripsy to the treatment of choice for fragmentation of most ureteral stones. Pneumatic lithotripsy consists of a pneumatically driven piston which will fragment stones by direct contact.
