Design Ideas

Based on current market of the holmium laser lithotripsy device power by manual control, the image recognition technology are presented by which are used in the stone therapy. ,in this paper，the core circuit, the external circuit and image recognition part of the circuit and software are discussed, and the corresponding Design ideas and programs is given. The system which can not only generate reliably, practically, high intelligently, but also can be widely applied to the treatment of ureteral stones, bladder stones and kidney stone.

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).

Objectives: The aim of this study was to assess the safety and effectiveness of ureteroscopy and Holmium: Yttrium-Aluminum-Garnet lithotripsy for the treatment of ureteral stones with different localizations in symptomatic pregnant women. Methods: A retrospective analysis was performed on 19 pregnant patients referred to our center between January 2005 and December 2012 with symptomatic hydronephrosis requiring surgical intervention. 7.5 F and 9.5 F semirigid ureterorenoscopy with Holmium laser lithotripsy was used for treatment in all patients. Complications were stratified according to modified Clavien criteria. Results: The mean age of patients was 25.4 (18-41) years, and the mean gestation duration was 24.8 (7-33) weeks. Six cases (31.5%) had a history of stone. Solitary kidney secondary to previous nephrectomy was observed in 2 patients and 1 patient had a hypoplastic kidney. Abdominal ultrasonography was used as the main diagnostic tool. Mean stone size was 9.2 mm (6-13). The location of the stones was the lower, middle, and upper ureter in 8 (42.1%), 5 (26.3%) and 6 (31.5%) cases, respectively. All stones were fragmented with Holmium laser lithotripsy. Of the 19 patients, 11 (57.8%) required doublr J stent insertion peroperatively. Intraoperative urological and obstetric complications were not observed. Postoperatively two complications were noted. According to Clavien criteria a complication was level 1, and the other was level 2. Conclusions: For treatment of pregnant women with symptomatic ureteral stones in every location, Holmium laser lithotripsy with a semirigid ureteroscopy can be used as judicious treatment. This approach is effective and safe with an acceptable complication rate.
