A retrospective review was performed on endoscopic holmium: YAG laser lithotripsy procedures performed to treat stones in children between March 2006 and March 2012. In total, 120 laser lithotripsy procedures were performed to treat 131 stones in 111 children (80 males and 31 females; age range, 11 months to 16 years; median age, 6 years). Stones were located in the kidney in 48 cases (36.7 %), ureter in 52 (39.7 %), bladder in 21 (16.0 %), and urethra in 10 (7.6 %). Stone size ranged from 4 to 30 mm (mean, 12.8 mm), and anesthesia duration was 10-170 min (mean, 56 min). Forty-four ureters required balloon dilation, and 61 double J stents were inserted. Follow-up ranged from 3 to 75 months (mean, 35 months). Complete stone clearance was achieved at the end of the procedure in 102 (91.9 %) patients (age < 7 years, 93.3 % vs. age ≥ 7 years, 90.2 %; p > 0.05). The success rate was 81.3 % for kidney stones (<10 mm, 90.9 % vs. ≥ 10 mm, 78.4 %; p > 0.05) and 100 % for the ureter, bladder, and urethral stones. Overall success rate with extracorporeal shockwave lithotripsy was 100 %. No major complications were encountered during or after the procedures. These results confirm the effectiveness and safety of holmium laser lithotripsy for treating all urinary stone locations in children of all ages.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-012-0495-x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30783790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients who applied to the emergency department with single, radio opaque ureteric stone of 5-20 mm size were included in the study. Patients were randomized into immediate and delayed SWL groups. SWL were carried out after pain relief in the delayed group. Maximum of three SWL sessions were applied to the patients with stones of 5 mm or bigger in diameter, leaving at least 3 days interval in-between. Stone-free rate after first session was similar in two groups. When CIRF was also considered as success, the success rate of SWL in the immediate SWL group was higher after first session (p = 0.02). Immediate SWL had a greater success rate in upper ureteric stones (p = 0.019). Overall average time required for elimination of stones was shorter in immediate SWL group than delayed SWL group (p = 0.033). The success rate after first SWL session (including CIRF) was 59 % for patients with chronic pain in the delayed group and 100 % for patients with acute pain in the immediate group. According to the hydronephrosis grade, success rates were 71 and 44.4 % for patients with grade 1 or no hydronephrosis in the immediate SWL group, and for patients with grade 2 or larger hydronephrosis in the delayed SWL group, respectively, after first SWL session. Immediate SWL insures stone-free status in a shorter time in cases with renal colicky pain and ureteral stones, particularly upper ureteral stones.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-012-0490-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30740037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty five patients with of bladder stones >2 cm and with benign prostatic hyperplasia were treated by transurethral cystolithotripsy with the SRS and TURP. The results in these patients were compared with 14 patients treated with current devices. In the SRS group, 26 patients had a single stone. Average stone size was 3.34 ± 1.03 cm, total operating time was 55.12 ± 19.95 min, and stone removal time was 23.30 ± 17.08 min. In the control group, 12 patients had a single stone. The average stone size was 2.46 ± 0.45 cm (larger stone size in SRS group, P < 0.05), total operating time was 79.85 ± 24.63 min (shorter operating time in SRS group, P < 0.05) and stone removal time was 43.28 ± 24.18 min the control group (shorter removal time in SRS group, P < 0.05). Mean stone size was 2.37 ± 1.18 cm and mean time to remove one stone was 12.57 ± 12.99 min in the SRS group. Mean stone size was 2.40 ± 0.48 cm (no significant difference between groups, P > 0.05) and mean time to remove one stone was 33.23 ± 25.26 min in the control group (shorter time in the SRA group, P < 0.001). No significant complication was found in the SRS group. This study suggests that multiple functions of SRS can be expected in transurethral cystolithotripsy. It can be used to fix stones during lithotripsy, and automatically collect stones and extract more stones through the sheath at one time during lithoextraction, which can reduce surgical time and damage to the bladder and urethra. This surgical procedure appears to be safe and efficient, and operating indications for transurethral cystolithotripsy could be expanded with this surgical procedure.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-012-0503-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30859260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-four rabbits are divided into six different groups. The first two groups evaluated as the control groups. After isolating the kidneys, we applied phenylephrine (Ph) and acetylcholine (Ach) in the first group and sodium nitroprusside (SNP) and histamine (H) in the second group. In the third, fourth, fifth and sixth groups, 14.5 kV shock wave (SW) was focused on the left kidneys. We adjusted the number of shocks to a total of 500, 1,500, and 3,000 SW, in the third, fourth and fifth groups, respectively. After isolating the kidneys, Ph, Ach was given in groups 3, 4 and 5. In the sixth group, to get the SNP and the H responses, 3,000 shocks modality was utilized. Marked contractile responses were obtained by phenylephrine in the control group. In kidneys that were exposed to 500 shocks SWL procedures, a decrease in contractile responses and hence, in perfusion pressures in different concentrations of phenylephrine was noted. However, a notable change in relaxation responses occurred after 3,000-shock applications. No difference in relaxation responses to nitroprusside, a direct vasodilating agent, was observed in any group, compared to the control group. Another cause of deterioration of renal hemodynamics after SWL can be attributed to the reduction in renal artery contraction-relaxation responses that result in the vascular smooth muscle and endothelial damage.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-012-0504-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30877041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 87 patients diagnosed with urolithiasis (495.5-530.8 mm(2)), percutaneous nephrolithotomy (PNL) was performed from 2000 to 2011. The patients were divided into three groups: Group A, 32 patients, PNL in the prone decubitus position; Group B, 24 patients, PNL in the dorsal supine position; Group C, 31 patients, PNL in the oblique supine position. We analyzed intraoperative parameters, complications, and results among the three groups. The three procedures were performed with a single access, 24-30 Ch. No statistically significant differences were found among the three groups regarding the patients' characteristics, or the morphology or size of the kidney stone treated. The operation time was shorter in the cases of PNL in dorsal supine and oblique supine compared to the prone position. The complication rate was very similar in the three groups. The main advantage of the PNL in oblique supine compared to the dorsal supine was that the puncture could in all cases be directed by ultrasonography, with greater precision, more safety, and more control of the percutaneous renal access. The oblique supine decubitus position is a safe position for the percutaneous treatment of urolithiasis and it becomes easier when the puncture is guided by ultrasound.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-012-0471-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30504839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
