ABSTRACT
Objective To investigate the effect of indwelling double-J ureteral stents before flexible ureteroscope lithotrity in terms of operation time, postoperative hospitalization time and operation effect. Methods All clinical data of flexible ureteroscope lithotrity from 2009 to 2013 were reviewed. Operation time, postoperative hospitalization time and recurrence rate of calculus of patients who received operation directly and patients who received indwelling of double-J ureteral stents 2 weeks before operation were observed and compared. Results Op-eration time, postoperative hospitalization time, and recurrence rate of calculus of patients who received indwelling of double-J ureteral stents 2 weeks before receiving operation were obviously lower than patients who received operation directly. Conclusion Operation time, postoper-ative hospitalization time and recurrence rate of calculus can be decreased by indwelling double-J ureteral stents 2 weeks before operation.
ABSTRACT
Objective To compare the clinical curative effect of partial tubeless and traditional percutaneous nephrolithotomy ( PCNL) in treatment of upper urinary calculus and to evaluate the clinical feasibility and value. Methods 206 patients with upper urinary calculus were enrolled in a randomized clinical trial from May 2013 to May 2014 according to the inclusion and exclusion criteria. These patients were randomized into the observation group (tubeless PCNL group) and the control group (traditional PCNL group). The operation time,stone clearance rate,visual analogue scale (VAS) pain score,usage of analgesic drugs,hemoglobin decrease,blood transfusion,bleeding,fever, leakage of urine,postoperative hospital stay,hospitalization expenses and the time of patients return to normal life were compared. Results All the operations were successfully finished. There were no statistically significant difference in operation time,stone clearance rate,hemoglo-bin decrease,bleeding,blood transfusion and fever (P>0. 05),but the visual analogue scale (VAS) pain score,usage of analgesic drugs, leakage of urine,postoperative hospital stay,hospitalization expenses and the time of patients return to normal life of the observation group were evidently lower than those of the control group (P<0. 05). Conclusion As partial tubeless PCNL have a great advantage on ease post-operative pain,shorten postoperative hospital stay,reduce hospitalization expenses and accelerate patients return to normal life,it is safe and effective for the treatment of upper urinary calculus,and it should be popularized and applied.
ABSTRACT
Objective To analyze the epidemiological status and risk factors of urinary calculus in residents of zhuo-zhou city. Methods A total of 19 446 residents in zhuozhou city were surveyed with a stratified random sampling method. The questionnaire included body mass index (BMI), daily water consumption, sweets, meals taste, cooking oil, high-protein diet and family history. A 1∶1 ratio was used to select the matched normal control group. Logistic regression analysis was used to compare BMI, diet habits, family history of renal stones and other risk factors of urinary calculus between two groups. Results There were 1 752 (9.8%) patients were confirmed as urinary calculus in 17 854 follow-up members, in which there were 1 125 male and 627 female. A total of 843 patients were at 0-40 years of age (48.04%). The incidence of urinary calculus was mainly in the second and third quarter of the year, and mainly was ureteral stones. There were significant differ-ences in BMI, daily water consumption, sweets, meals taste, cooking oil, high-protein diet and family history between two groups. Logistic regression analysis showed that the protective factors included more daily water consumption, lower level of BMI and eating vegetable oil. And the risk factors of urinary calculus were salty taste, sweet taste, high protein diet and fami-ly history of urinary calculus. Conclusion Prevention measures of urinary calculus included controlling body mass, drink-ing more water, and controlling high-protein, high-sugar, high-salt food intake.
ABSTRACT
PURPOSE: We aimed to compare the effects of a fast shock wave rate (120 shocks per minute) and a slow shock wave rate (60 shocks per minute) on the shock wave lithotripsy (SWL) success rate, patient's pain tolerance, and complications. MATERIALS AND METHODS: A total of 165 patients with radiopaque renal pelvis or upper ureter stones were included in the study. Patients were classified by use of a random numbers table. Group I (81 patients) received 60 shock waves per minute and group II (84 patients) received 120 shock waves per minute. For each session, the success rate, pain measurement, and complication rate were recorded. RESULTS: No statistically significant differences were observed in the patients according to age, sex, body mass index, stone size, side, location, total energy level, or number of shocks. The success rate of the first session was greater in group I than in group II (p=0.002). The visual analogue pain scale was lower in group I than in group II (p=0.001). The total number of sessions to success and the complication rate were significantly lower in group I than in group II (p=0.001). CONCLUSIONS: The success rate of SWL is dependent on the interval between the shock waves. If the time between the shock waves is short, the rate of lithotripsy success decreases, and the pain measurement score and complications increase. We conclude slow SWL is the optimal shock wave rate.

Objective To summarize the experience of management of upper urinary tract calculi by Extracorporeal Shock Wave Lithotripsy (ESWL) in our department in order to improve the gravel success rate and decrease the incidence of complications.Methods 15 019 patients with upper urinary calculi from October 1988 to September 2011 treated by ESWL with X-ray localization were analyzed retrospectively.The maximum diameter of the stones ranged from 0.8 cm to 3.2 cm,with 1 3 794 cases with maximum stone diameter less than 2 cm (guoup A),and with 1225 cases with maximum stone diameter more than 2 cm (guoup B).All patients had normal or nearly normal renal function,and 56.0％ patients (8 410/15 019)had varying degrees of hydronephrosis.Results The effective rate of first ESWL was 84.5％ ( 12 691/15 019) and the effective rate of second ESWL was 12.0％ (1 802/15 019),and 313 cases need a third ESWL.The clearance rate in group A was 90.2％ ( 12 443/13 794 ),in group B was 50.9％ (623/1225),and the overall stone clearance rate within three months was 87.0％ ( 13 066/15 019).The majority of patients ( about 93％ ) had postoperative gross hematuria,which disappeared after drinking lots of water.46cases (0.3％) of patients had postoperative fever,which returned to normal after usage of antibiotics.There were no serious complications such as kidney hematoma,continuous high fever,continuous hematuria,ureteral stones jams.Conclusions ESWL.with X-ray localization had the advantage of low energy,minor injury,easy localization,uniform stone fragment,because of which it could reduce the complications such as continuity fever,ureter stone james,continuious hematuria.ESWL with X-ray localization could be preferred treatment for upper urinary calculi with diameters between 10 to 20 mm.
ABSTRACT
O estudo teve como objetivo avaliar os casos de urolitíase canina em que a composição mineral dos urólitos foi analisada quantitativamente. Foi avaliada quantitativamente a composição mineral de 156 urólitos obtidos de cães (nefrólitos, ureterólitos, urocistólitos e uretrólitos). Desse total, 79,5 por cento (n=124) eram simples, 18 por cento (n=28) eram compostos e apenas 2,5 por cento (n=4) eram mistos. A estruvita foi o tipo mineral mais frequente nos urólitos simples (47,6 por cento; n=59), em todos os mistos (100 por cento; n=4) e nas camadas núcleo e pedra de urólitos compostos (32,1 e 75 por cento, respectivamente). O oxalato de cálcio foi o segundo mineral mais frequente dos urólitos simples (37,9 por cento, n=47). Ao contrário do que é preconizado para os urólitos simples, as recomendações para o tratamento de urólitos compostos são mais complexas, tais como protocolos de tratamento de dissolução diferentes (se composto por minerais distintos e passíveis de dissolução como urato e estruvita). Além disso, a dissolução pode não ser viável, caso ocorra presença de material insolúvel envolvendo o urólito ou se este representar mais de 20 por cento da camada. Vinte e dois urólitos compostos (78,7 por cento) apresentaram uma camada externa não passível de dissolução (oxalato de cálcio ou fosfato de cálcio); dois (7,1 por cento) apresentaram camadas externas passíveis de dissolução (estruvita ou urato), porém camadas mais internas não solúveis, o que permitiria apenas a dissolução parcial do urólito. Assim, o conhecimento da composição de todas as camadas que compõem o urólito é essencial para o entendimento da formação do cálculo e consequentemente para a indicação do tratamento adequado, assim como para prevenção de recidivas.
The aim of this study was to evaluate dogs with urolithiasis in which mineral composition of calculi was quantitatively analyzed. Quantitative mineral composition was performed in 156 canine uroliths. Simple uroliths represented 79.5 percent (n=124) of the cases, 18 percent were compound (n=28) and only 2.5 percent (n=4) of the calculi were mixed. Struvite was the most frequent mineral type of simple uroliths (47.6 percent; n=59) as well as in all mixed (100 percent; n=4) and in the core and stone uroliths (32.1 percent and 75 percent, respectively). Calcium oxalate was the second more frequent mineral composition of simple uroliths (37.9 percent; n=47). Unlike simple uroliths, recommendation for the treatment of compound uroliths is more complex, and diet protocols for calculi dissolution may be different when the calculus is composed by different minerals that are possible to be dissolved (e.g. urate and stuvite). Besides, dissolution may not be feasible if it occurs in presence of insoluble material involving urolith or if it represents more than 20 percent of the layer. Twenty two compound uroliths (78.7 percent) presented an external layer that was not possible to be dissolved (calcium oxalate or calcium phosphate); two calculi (7.1 percent) had superficial layers dissolvable (struvite or urate), but inner layers were not soluble, which allowed only partial dissolution of urolith. Knowledge of all urolith layers mineral composition is essential for the understanding of calculus formation and for the adequate treatment indication as well as for the procedures to prevent recurrence.

ABSTRACT
443) ?mol/L) due to upper urinary calculous obstruction,urgently treated by pneumatic lithotripsy(EMS,Switzerland) under ureteroscopy,from August 2002 to April 2006 in this hospital.After stone fragmentation and removal,an indwelling double-J stent was placed into the ureter at the same time.Results The continuity of the ureter was restored after one session of lithotripsy in all the 9 cases(14 sides).The ureteral calculi were thoroughly removed on one session in 7 cases(12 sides).Few residual stones were found in the renal pelvis in 2 cases(2 sides),in one of which the stones were spontaneously expelled after oral medication,and in another,after extracorporeal shock wave lithotripsy(ESWL).No severe complications happened,such as ureteral avulsion,rupture,or perforation.Concentrations of serum creatine were decreased to normal levels within 3~7 days after operation in all the 9 cases.The gross blood urine disappeared in 1~4 days postoperatively.The patients were discharged from the hospital after 3~7 days (mean,5 days) after operation.The double-J catheter was removed at 1~2 months postoperatively.Follow-up examinations in 7 cases for 2~30 months(mean,14 months) found normal levels of serum creatine and no recurrent urinary stones under B-ultrasonography or X-ray radiography.Conclusions Ureteroscopic pneumatic lithotripsy in the treatment of acute renal failure due to upper urinary calculous obstruction is an effective treatment with short operation time,safety,and minimal trauma.By using this procedure,both sides of ureteral stones can be removed on one session.
ABSTRACT
Objective To evaluate the efficacy and safety of percutaneous nephroscopic lithotripsy for the treatment of bilateral upper urinary calculi. Methods From July 2004 to December 2008,we performed percutaneous nephroscopic lithotripsy under X-ray or ultrasonic guidance for 35 patients with bilateral upper urinary calculi. Of the 35 patients,bilateral renal calculi were found in 18 patients,unilateral renal and unilateral ureteral calculus in 10,bilateral ureteral calculi in 7. Results In 35 patients (70 sides),the calculi was removed through a single tract in 49 sides,through double tracts in 18 sides,and through triple tracts in 3 sides. The mean operation time for unilateral PCNL was 66 min (ranged from 20 to 185 min). The stone-free rate was 80% (56/70) on one session. A second-look stone removal was needed in 8 laterals,and 3 laterals underwent three times of lithotomy. In three sides,a few residual renal stones were found after the first operation,but no second operation was performed. The final stone-free rate was 91.4% (64/70) in all of the cases,among which the stone-free rate was 100% (24/24) for ureteral stones and was 87% (40/46) for renal stones. In this series,no chest or abdominal injuries,intestinal perforation,or injuries to surrounding organs were detected. The patients were discharged from hospital in 5 to 30 days,and then were followed up for 3 to 6 months. During the follow-up,B-ultrasonography and KUB+IVP found no recurrence of calculi. Conclusions Percutaneous nephrolithotomy is effective and safe for bilateral upper urinary calculi. By skilled urologists in conditioned hospital,simultaneous bilateral percutaneous nephrolithotomy performed on bilateral upper urinary calculi can shorten the cycle time of treatment and hospitalization.

ABSTRACT
From 1992 to 1997, 982 calculus in the upper urinary tract (UUT) was removed. There were 10 acute renal failure and 75 chronic renal failures. The study deserves special commentaries. Renal failure occurred in both groups patients bilateral calculi (group I) and calculus in the single kidney (group II). The members of chronic renal failure were much higher than that of acute renal failure. Renal failure in group II was 2.24 time higher than in group I. The risk was equal for both sex. In group I, the rate of renal failure increased with long history of disease and patients in very short time. Among high - risk factors for renal failure we noted: calculus in many location, bilateral Staghorn calculus multiple bilateral calculi or calculi with calculi in the single kidney, calculi urinary tract infection. Roentgenography, ultrasound, and radioisotope examinations were used as non-invasive techniques for those patients
