低能级体外冲击波碎石治疗肾鹿角形结石

目的探讨低能级体外冲击波碎石(extracorporeal shock wave lithortripsy,ESWL)治疗肾鹿角形结石的效果. 方法对18例鹿角形结石进行体外冲击波治疗.碎石能级1～3级,冲击次数1 800～3 000次,脉冲间隔60 ～80次/min,工作电压10～12.75 kV. 若结石直径>3 cm,在碎石前预先插入双J管,防止石街形成.对直径>4 mm的残余结石,再次行ESWL,直至结石完全消失. 结果所有病人耐受良好,治疗结束能自行回家.除1例碎石失败外,余17例经ESWL治疗成功.治疗3～9次,至完全排除结石.66例次(66/77,85.7%)术后有1～2次肉眼血尿.5例出现石街,长1.9～5.2 cm,4例石街经再次碎石成功,1例输尿管镜取石. 结论低能级ESWL治疗肾鹿角形结石是一种安全、有效的方法.     

尿结石理化性质检测在体外冲击波碎石中的意义

对３２例的尿结石采用化学定量分析法进行化学成分分析，利用材料力学原理和方 法测定密度、硬度和抗压强度，并对其中１３例的尿结石作体外碎石试验。结果表明碎石所需 冲击次数与结石成分有关，尤其是草酸钙结石所需冲击次数明显增加；冲击次数与结石物理特 性有关，随结石硬度增加而增加。因此，检测尿结石理化性质在体外冲击波碎石中具有重要意 义。     

Intraductal shock-wave lithotripsy in complicated common bile duct stones

Summary Intracorporeal shockwave lithotripsy was performed in 36 patients with problematic common bile duct stones. All of the patients had undergone unsuccessful mechanical lithotripsy prior to this procedure. In 29 patients (80.6%), the stones were fragmented under cholangioscopic control and subsequently extracted with a Dormia basket. In seven patients, the procedure failed due to stone impaction or failure to intubate the common bile duct with a nasobiliary tube. No complications were observed. Cholangioscopically guided intracorporeal shockwave lithotripsy is a highly effective and safe procedure for the conservative treatment of complicated common bile duct stones.Abbreviations ESWL extracorporeal shock-wave lithotripsy - ISWL intracorporeal shock-wave lithotripsy Dedicated to Prof. Dr. med.

Comparison of the efficacy of low-intensity shock wave therapy and its combination with platelet-rich plasma in patients with erectile dysfunction

We aimed to compare the efficacy of low-intensity shock wave therapy (Li-SWT) alone and its combination with platelet-rich plasma (PRP) in the treatment of patients with erectile dysfunction (ED). Between January 2015 and October 2020, patients who did not benefit from the use of phosphodiesterase type 5 inhibitors (PDE5i; 5 mg/day) for at least 3 months and underwent Li-SWT or Li-SWT with PRP were evaluated retrospectively. There were 93 patients who were subjected to Li-SWT only (Group 1) and 91 patients subjected to Li-SWT with PRP (Group 2). Analysis of the International Index of Erectile Function-Erectile Function Area (IIEF-EF) scores showed a significant increase in both the groups post-treatment (Group 1: from 14.33 ± 4.39 to 23.8 ± 4.37, p = .001; Group 2: from 17.82 ± 3.44 to 26.3 ± 2.55, p = .001). When the increase in the IIEF-EF scores was compared pre- and post-treatment between the groups with respect to the ED grades, there was no statistically significant difference between them. Furthermore, while the intravaginal ejaculatory latency time (IELT) in successfully treated patients of Group 1 remained the same, Group 2 presented 1.5–3.5 times (mean, 2.4) prolongation. Their mean IELT score showed an increase from 2.2 (0.8–3.5) min to 5.3 (2.8–10.5) min. Our study shows that combination treatment of Li-SWT with PRP injections is not only safe for patients with ED, but also effective and safe in prolonging the IELT.     

聚焦式体外冲击波联合离心锻炼治疗大转子疼痛综合征

目的：探讨聚焦式体外冲击波联合离心锻炼治疗股骨大转子疼痛综合征的临床疗效。方法：2017年9月至2019年6月,将符合研究标准的53例股骨大转子疼痛综合征（greater trochanteric pain syndrome,GTPS）的患者分为观察组（29例）和对照组（24例）。观察组,男8例,女21例,年龄38~62（49.96±6.39）岁,病程6~13（8.58±1.99）个月,采用聚焦式体外冲击波联合离心锻炼治疗;对照组,男5例,女19例,年龄39~62（52.79±5.86）岁,病程6~14（9.04±2.51）个月,单纯采用离心锻炼治疗。分别使用疼痛视觉模拟评分（visual analogue scale,VAS）和髋关节Harris评分评估两组患者治疗前及治疗后1、2、6个月时髋部疼痛缓解程度及髋关节功能恢复情况,比较治疗效果。结果：治疗后1个月,两组VAS、髋关节Harris评分及治疗成功率比较差异无统计学意义（P>0.05）;2个月时,观察组VAS （3.20±0.81）分低于对照组的（3.87±0.61）分（P<0.05）,髋关节Harris评分（81.93±2.43）分与对照组（82.12±2.34）分比较差异无统计学意义（P=0.770）,治疗成功率（58.62%,17/29）高于对照组（29.16%,7/24）（P=0.032）;6个月时,观察组VAS （2.24±0.68）分低于对照组的（3.12±0.53）分（P<0.001）,髋关节Harris评分（85.10±1.75）分高于对照组的（83.66±1.78）分（P=0.005）,治疗成功率（82.75%,24/29）与对照组（62.50%,15/24）比较差异无统计学意义（P=0.096）。结论：聚焦式体外冲击波联合离心锻炼能够显著缓解大转子疼痛综合征患者髋部疼痛症状,改善髋关节功能,安全性可靠,值得在临床实践中应用推广。     

Repeated piezoelectric lithotripsy for gallstones with and without ursodeoxycholic acid dissolution: A multicenter study

The use of bile acid dissolution therapy in extracorporeal shockwave lithotripsy of gallstones, remains controversial. Our study examined whether chemolitholysis after sufficient disintegration enhanced stone clearance within 6 months of the first lithotripsy. A total of 143 patients who developed one to three radiolucent stones measuring⪯30 mm in diameter were randomly separated into two treatment groups: 47% were given lithotripsy alone, and 53% lithotripsy plus ursodeoxycholic acid (UDCA). Repeated piezoelectric lithotripsy was given, with no limit on the total number of treatment sessions, to pulverize or disintegrate stones into fragments<3 mm. Stones were disintegrated in 97% of all patients, and the fragments were ⪯2 mm in 50% of these patients. According to an intention-to-treat analysis, 52% in the lithotripsy alone group and 58% in the UDCA group were free of stones 6 months after the first lithotripsy (P=0.61). Of the patients with fragments⪯2 mm, 71% in the former and 86% in the latter group were free of stones 6 months after the first lithotripsy, with no significant difference between the groups. Biliary pain occurred in 25% of all patients, including 3 with acute cholecystitis. We concluded that the sufficient disintegration of gallstones achieved with repeated lithotripsy enhanced the early clearance of fragments, regardless of whether chemolitholysis was employed.

Stent underexpansion due to heavy coronary calcification resistant to rotational atherectomy: A case for coronary lithoplasty?

Stent underexpansion is frequently observed in calcified coronary lesions and increases the risk of future adverse cardiac events. Current plaquemodification techniques might not be suitable when calcium deposition is circumferential and deep inside the vessel wall. We report a case during which coronary lithoplasty was used as an adjuvant therapy to improve severe stent underexpansion after failed atherectomy and high‐pressure non‐compliant balloon dilatations.
