Neodymium:Yttrium Aluminum Garnet Laser for Mini-Percutaneous Treatment of Upper urinary Tract stones

Journal of Huazhong University of Science and Technology(Medical Sciences) 2007年第2期27卷 197-199页

作者：罗洪波刘修恒吕胜启 Department of Urology Renmin Hospital of Wuhan University

To observe the efficacy and safety of mini-percutaneous nephrolithotomy with Neodymium：Yttrium Aluminum Garnet （Nd-YAG） laser in the treatment for upper urinary tract stones, from December 2005 to September 2006, 31 patients with renal stones, 15 patients with ureteral stones and 7 patients with renal and ureteral stones underwent mini-percutaneous nephrolithotomy with Nd-YAG laser by combination of rigid ureteroscope and flexible ureteroscope under B-ultrasound guidance. Clinical data including operation time, lithotripsy time, complications and stone-free rate were analyzed retrospectively. Our study showed that the percutaneous renal access （F14-F18） was successfully established under B-ultrasound guidance in all cases. Immediate phase Ⅰ lithotripsy was performed in 47 cases through single tract, and in one case through two tracts. Delayed phase Ⅱ lithotripsy was done in 5 cases of renal stones. Operation time ranged from 55 to 180 rain with an average time of 100±15 min. Lithotripsy time was from 25 to 135 min and the average lithotripsy time was 65±11 min. No severe complications occurred in our series. Complex renal stones were cleared in 34 of 38 cases （89.5 %）. All ureteral stones were completely removed in 15 cases （100 %）. It was concluded that mini-percutaneous nephrolithotomy with Nd：YAG laser for the treatment of upper urinary tract stones by combination of rigid ureteroscope and flexible ureteroscope has the advantages of effectiveness, mini-invasion, shorter operative time and safety.

Computed tomography(CT) is widely used to examine stones in the urinary *** addition to the size and location of the stone and the overall health of the kidney,CT can also assess the density of the stone in Hounsfield units(HU).The HU,or Hounsfield density,measured by CT,is related to the density of the tissue or stone.A number of studies have assessed the use of HU in *** have been used to predict the type and opacity of stones during diagnosis,and the efficacy has been assessed using methods including extracorporeal shock wave lithotripsy(ESWL),percutaneous nephrolithotomy(PCNL),ureterorenoscopic ureterolithotripsy(URSL),and medical expulsive treatment(MET).Previous studies have focused on the success rate of HU for predicting the type of stone and of ESWL *** the composition of the stone plays a key role in determining the most appropriate treatment *** most recent reports have suggested that the HU value and its variants facilitate prediction of stone ***,the inclusion of data regarding urine,such as pH and presence of crystals,increases the predictive ***,which now form part of the clinical guidelines,allow us to predict the success of ESWL; therefore,they should be takeninto account when ESWL is considered as a treatment ***,there are currently insufficient data available regarding the value of HU for assessing the efficacy of PCNL,URSL,and *** performed to date suggest that these values would make a significant contribution to the diagnosis and treatment of urinary system ***,more data are required to assess this further.

Research Progress on Flexible Ureteroscopy

引用

Journal of Biosciences and Medicines 2024年第9期12卷 54-61页

作者： Zuwei Wang Haitao Dai Urology Department The First Affiliated Hospital of Yangtze University Jingzhou China

The ureteroscopic surgical technique has developed rapidly in recent years and has become an important method of urological surgery. The manufacturing and production of corresponding ureteroscopes are also constantly improving. This article systematically reviews and analyzes existing literature, summarizes the characteristics of various ureteroscopes in recent years, studies the advantages and disadvantages of ureteroscopes with different characteristics, summarizes relevant clinical experience in the use of ureteroscopes, and provides preliminary prospects for the future development of ureteroscopes. The results indicate that disposable electronic ureteroscopes and robotic ureteroscope systems may be an important development direction in the future.

泌尿系结石是一种常见的泌尿系统疾病，其成分多样，包括草酸钙、磷酸钙、尿酸等。近年来，关于结石成分对结石术后患者功能影响的研究逐渐增多。这些研究揭示了不同结石成分对术后肾功能、疼痛感知、生活质量及并发症风险的不同影响。本文综述了近年来关于泌尿系结石成分对术后患者功能影响的研究进展，重点探讨了不同结石成分在术后肾功能、疼痛感知、生活质量及并发症风险方面的差异，并对未来的研究方向提出了建议。研究结果表明，草酸钙和磷酸钙结石更容易导致术后肾功能受损和疼痛，而尿酸结石对肾功能和疼痛的影响较小。未来的研究应关注多因素综合分析、大样本量和多中心研究、长期随访研究等方面，以进一步揭示结石成分对术后患者功能的影响，制定个体化的治疗方案和预防措施，提高术后患者的治疗效果和生活质量。

Objective:To measure oxalate,calcium,and sodium contents of traditional Chinese medicines(TCMs)that are commonly used to prevent and dissolve urinary stones to exclude the possibility that long-term use of such medicines promotes stone *** second objective was to measure citrate,potassium,and magnesium contents in the same medicines to provide possible clues about the mechanisms of prevention and dissolution of urinary stones by ***:Ten of the most commonly-used TCMs for preventing and dissolving urinary stones were chosen and subjected to ion chromatography(IC)to measure water-soluble and total oxalate and citrate *** coupled plasma atomic emission spectrometry(ICPAES)was used to measure calcium,potassium,magnesium,and sodium contents in a water extract and in digestion ***:Average contents of water-soluble oxalate,calcium,and sodium in the water extract were 41.92,84.32,and 22.82 mg/100 g,respectively,far below the normal dietary intake of adults in *** average contents of citrate and magnesium in water extracts were 268.99 and 66.65 mg/100 g,respectively,below the recommended intake for *** ion contents are therefore insufficient to inhibit the formation of urinary *** average content of potassium in the water extract was 867.71 mg/100 g,which was relatively abundant,so taking the prescription used in this experimental protocol can increase the body’s potassium content to some ***:Long-term use of TCMs would not increase the risk of urinary stone *** potassium content in TCMs is high,which is one possible reason for the prevention of urinary stones by TCMs.
