OBJECTIVE: Stone analysis is an important examination for treatment and prevention of recurrence in urolithiasis. A twenty-six years clinical study of patient with urinary stone formers performed stone analysis was conducted. MATERIALS AND METHODS: 1,108 stone formers (male 726, female 382) who performed stone analysis from 1977 to 2002 was conducted. Location of the stone, sex, age, treatment and stone analysis was examined in this study. Phase 1 is from 1977 to 1983 mainly performed open surgery, phase 2 is from 1984 to 1992 mainly performed endoscopic surgery, and phase 3 is from 1993 to 2002 mainly performed extracorporeal shock wave lithotripsy (SWL). RESULTS: Analytic numbers per year increased, especially phase 3. In the treatment of upper urinary tract (UUT) stone, open surgery, endoscopic surgery and SWL was carried out 78.4%, 72.8% and 71.4% of all cases in each phase. Many transurethral lithotripsy were performed for lower urinary tract (LUT) stone. The numbers of UUT and LUT stone were 1,007 and 101 cases. The frequency of LUT stone was higher than that found in a nationwide urolithiasis survey carried out in Japan in 1995. The male-female ratio of UUT stone was 2.35:1, 1.74:1 in phase 2 and 3. The frequency of female increased in phase 2 more than that in phase 3. The incidence of calcium oxalate stone was increased, calcium phosphate stone and infectious stone was significantly decreased in UUT and calcium containing stone in LUT was decreased. The average age for incidence of UUT stone rose in man step by step. The frequency in male was significantly higher than that in female under 50's, not significantly higher over 50's in calcium oxalate with calcium phosphate stone former (p = 0.009). CONCLUSION: In the present study, the clinical features were as follows : important urinary stone analysis, high frequency of LUT stone, high frequency in females, tendency to aging, high frequency of calcium containing stone in LUT, resolution of the difference in male and female over 50's in calcium oxalate with calcium phosphate stone former. 相似文献

OBJECTIVES: This study was performed to look for an improvement of therapeutic strategies with regard to the treatment of uric acid stones using artificial stones made of uric acid (BON(N)-STONES) which are comparable to their natural counterparts. MATERIALS AND METHODS: Using an experimental arrangement simulating the physiological conditions in the upper urinary tract the efficacy of different alkaline solutions and artificial urine in dissolving artificial uric acid stones (BON(N)-STONES) was investigated. The dissolution of natural uric acid stones was measured and investigations on shock wave lithotripsy (SWL) combined with initial chemolytic treatment of the stones were performed. RESULTS: The efficacy of alkaline solutions, especially THAM at a pH of 10, in dissolving artificial uric acid stones was demonstrated. The investigations on SWL showed a significant improvement on stone comminution of artificial uric acid stones after initial chemolytic treatment with THAM. CONCLUSIONS: New basics to improve dissolution of uric acid stones have been developed by performing standardized in vitro investigations. The suggestion was confirmed that stone fragility and thus SWL can be improved by varying the physical properties of uric acid stones through initial treatment with THAM solution. 相似文献

PURPOSE: To elucidate the frequency and adversity of the effects of shockwave lithotripsy (SWL) on the male reproductive system. We investigated the possible alterations in the quality of semen in patients treated by SWL for pelvic ureteral stones. PATIENTS AND METHODS: The semen of 10 men was examined 1 day before and 5 and 90 days after SWL for distal ureteral stones, in accordance with the World Health Organisation guidelines. The results were compared with those from the semen samples of 10 healthy male volunteers undergoing SWL for calculi of the upper urinary tract. RESULTS: Microscopic analysis of the semen samples revealed a transient decline in sperm density (24.7%), sperm motility (10%), sperm vitality (8%), and seminal fructose (27.5%) after SWL for distal ureteral stones. A distinctly higher number of spermatozoa of pathological origin was detected after SWL in the same group. There was no trace of microscopic hemospermia before shockwave treatment, but it was detected in 90% of the patients with lower ureteral calculi after SWL. Macroscopic hemospermia was detected in two of these nine patients. No deterioration of the semen characteristics and no hemospermia was observed after treatment in the control group with upper urinary stones. CONCLUSIONS: Our investigations confirmed a transient deterioration in semen quality after SWL for distal ureteral calculi, whereas no deterioration was observed after SWL for upper ureteral stones. Impaired sperm quality values returned to normal within 12 weeks after SWL, clearly indicating a damaging effect of SWL on seminal vesicle or ejaculatory duct function. The initial procreative capacity was restored in all patients. 相似文献

BACKGROUND: The changes over time of the annual incidence of lower urinary tract stones in Japan from 1965 to 1995 were analyzed. METHODS: Data on lower urinary tract calculi were abstracted from the past three nationwide surveys of urolithiasis, which covered nearly all major hospitals and urologists in Japan and enumerated all outpatient visits diagnosed as urolithiasis in the years 1965, 1975, 1985 and 1995. Chronological changes in the sex- and age-related annual incidences of lower urinary tract stones and stone composition were estimated. RESULTS: Lower urinary tract stones were predominant in men 60 years of age or older. Between 1965 and 1995, the annual incidence has significantly decreased in men > or = 60 years of age from 37.2 to 27.0 per 100000 and significantly increased in women > or = 60 years of age from 2.4 to 4.8 per 100000. In men, an increased proportion of uric acid and calcium stones as well as a decreased frequency of infection stones is a phenomenon common to upper urinary tract stones. However, infection and calcium stones have been two major stone types in women. CONCLUSIONS: In contrast to upper urinary tract calculi, the incidence of lower urinary tract stones has decreased over the last 30 years in men > or = 60 years of age predisposed to this disease. 相似文献

Extracorporeal shock wave lithotripsy (SWL) is the current treatment modality of choice for upper urinary tract calculi. For stones with a diameter >2 cm and in lower calyceal stones and diverticular stones, the stone-free rate of SWL is rather poor. In these cases, conventional percutaneous nephrolithotomy (PCNL) leads to an increased stone-free rate, but morbidity with conventional PCNL is significant higher than in SWL. With the invention of miniaturized nephroscopes (mini-perc), new treatment options are available. The experience based on hundreds of treatments using mini-perc show comparable results of mini-perc to conventional PCNL and a complication rate comparable to that for SWL. These favorable results are independent of stone size, stone location, and patient age. In summary, mini-perc can be recommended as a primary approach to stones of the upper urinary tract exceeding 1 cm, larger lower-pole stones, and calyceal diverticular stones. Mini-perc can be regarded as an alternative treatment modality to conventional PCNL. 相似文献

OBJECTIVES: This study was performed to look for an improvement of therapeutic strategies with regard to the treatment of infectious urinary stones using artificial stones made of struvite and apatite ('Bon(n) stones') which are comparable to their natural counterparts. MATERIALS AND METHODS: Using an experimental arrangement simulating the physiological conditions in the upper urinary tract, the efficacy of artificial urine (pH 5.7), Suby G solution (pH 3.6), mixtures of artificial urine with Suby G (pH 3.9 and pH 4.1) in dissolving artificial struvite and apatite stones (Bon(n) stones) was investigated. The dissolution of natural infectious urinary stones was also measured. Additionally, investigations on shock-wave lithotripsy (SWL) combined with initial chemolytic treatment of the stones were performed. RESULTS: The efficacy of Suby G solution in dissolving artificial stones was demonstrated. Direct comparison of chemolysis of natural and artificial stones showed no statistical difference between infectious urinary stones and Bon(n) stones of the same material. The investigations on SWL showed a significant improvement on stone comminution, especially of artificial apatite stones after initial chemolytic treatment with Suby G. CONCLUSION: New basics to improve dissolution of infectious urinary stones have been developed by performing standardized in vitro investigations. Local chemolysis with Suby G is an effective tool in the treatment of infectious stone disease. SWL can be improved by varying the physical properties of infectious stones through initial treatment with Suby G solution. 相似文献

PurposeWe report our experience with retrograde intrarenal lithotripsy (RIRL) for renal stones not alleviated by shock wave lithotripsy (SWL).Materials and MethodsA total of 28 females and 53 males with a mean age of 53 years (range 18 to 86) were studied. They had been treated with a mean of 3.2 previous SWLs. Mean stone size was 9.2 mm (range 4 to 22) and the mean number of stones per patient was 1.27 (range 1 to 5) for a total of 103 stones overall. In 70 patients there was 1 stone. Rigid and flexible ureteroscopes were used in 8 and 67 cases, respectively, while a combined approach was used in 6. A holmium:YAG laser was used for fragmentation in 52 patients. Success was defined as stone-free status or residual fragments less than 3 mm.ResultsThe overall success rate was 67%. RIRL yielded a 46% stone-free rate. Of the 44 patients 17 (39%) had residual stones less than 3 mm, while 13 required ancillary procedures. There were no residual ureteral stones. Original stone size correlated inversely with the success rate. Most failures involved lower pole stones, in that laser fiber deflection prevented reaching them in 9 cases. The procedure was interrupted due to extravasation or bleeding in 5 patients and 6 had postoperative urinary tract infections (16% overall complication rate).ConclusionsRIRL effectively and safely alleviated upper tract stones unresponsive to earlier SWL. It can be considered salvage therapy in such cases. RIRL is well suited for treating stones less than 2 cm with better stone-free rates than SWL in the same circumstances. Residual stones were more likely in lower pole cases. 相似文献

BACKGROUND AND PURPOSE: To evaluate the efficacy of potassium citrate treatment in preventing stone recurrences and residual fragments after shockwave lithotripsy (SWL) for lower pole calcium oxalate urolithiasis. PATIENTS AND METHODS: One hundred ten patients who underwent SWL because of lower caliceal stones and who were stone free or who had residual stone 4 weeks later were enrolled in the study. The average patient age was 41.7 years. All patients had documented simple calcium oxalate lithiasis without urinary tract infection and with normal renal morphology and function. Four weeks after SWL, patients who were stone free (N = 56) and patients who had residual stones (N = 34) were independently randomized into two subgroups that were matched for sex, age, and urinary values of citrate, calcium, and uric acid. One group was given oral potassium citrate 60 mEq per day, and the other group served as controls. RESULTS: In patients who were stone free after SWL and receiving medical treatment, the stone recurrence rate at 12 months was 0 whereas untreated patients showed a 28.5% stone recurrence rate (P < 0.05). Similarly, in the residual fragment group, the medically treated patients had a significantly greater remission rate than the untreated patients (44.5 v 12.5%; P < 0.05). CONCLUSION: Potassium citrate therapy significantly alleviated calcium oxalate stone activity after SWL for lower pole stones in patients who were stone free. An important observation was the beneficial effect of medical treatment on stone activity after SWL among patients with residual calculi. 相似文献

Toyooka Hospital is a central hospital in Tajima, a rural area in the northern part of Hyogo Prefecture. Because we possess the sole lithotripter in this area, almost all urolithiasis patients requiring treatment have been referred to our department. Based on the number of urolithiasis patients treated in our institution, we estimated the annual prevalence and incidence of upper urinary tract stones in the Tajima area. The mean annual prevalence of urolithiasis and incidence during the 1991-1993 period were 141 and 93 per 100,000, respectively. The male to female ratio was 2.0 to 1 in prevalence and 2.2 to 1.0 in incidence. Prevalence was highest in the sixties (245) and fifties (235), followed by the forties (205), seventies (162) and thirties (160). The incidence was highest in the fifties (169), followed by the forties (147), sixties (145) and thirties (118). In consideration of sex, the incidence was highest in males in the fifties and the forties. Of the patients with upper urinary calculi, 23.1% were treated by extracorporeal shock wave lithotripsy, while in 23.8% stones passed spontaneously and 50.9% were followed up without treatment. On stone analysis, calcium oxalate and/or calcium phosphate was present in 75.6%, uric acid in 16.4%, struvite and/or carbonate apatite in 5.6% and cystine in 1.4%. In summary, the prevalence and incidence of upper urinary tract calculi in the Tajima area were considerably higher than those in the nationwide survey on urolithiasis in Japan conducted in 1985. 相似文献

OBJECTIVE: The aim of this randomized study was to assess the relation between shockwave frequency, sedation, and efficiency in piezoelectric extracorporeal shockwave lithotripsy (SWL) for ureteral calculi. METHODS: A random sample of 114 patients aged between 15 and 74 (mean 45) years were treated at the shockwave frequencies of 1 (N = 57) or 4 (N = 57) per second using the EDAP LT 02 lithotripter at maximum energy. The stones' largest diameter ranged from 5 to 18 mm (mean 7.6 mm). Lower ureteral stones were treated with the patient in the prone position and upper ureteral stones in supine position. The duration of SWL sessions and stone measurements were statistically similar for patients treated at low and high frequencies. The levels of required sedation (none, intramuscular analgesia, intravenous sedation-analgesia) and stone-free rates after one session were analyzed by Student's t-test or Fisher's exact test. RESULTS: Sedation did not differ statistically with SWL frequency for mid and lower ureteral calculi. However, the use of intravenous sedation-analgesia was less common for patients with upper ureteral stones treated at low rather than high frequency (19% and 100%, respectively; P < 0.0001). The success rate was significantly lower (P = 0.04) for lower ureteral calculi treated at low v high frequency (65 % and 89%, respectively) but was not statistically affected by frequency for upper ureteral stones. CONCLUSION: We recommend high frequency for piezoelectric SWL of lower ureteral calculi, especially for stones with a maximum diameter > or =8 mm. On the other hand, low-frequency SWL appears to be suitable for the treatment of upper ureteral stones. 相似文献

Between August 1987 and December 1990, 546 patients were admitted to the department of Urology at the Poh Ai Hospital of I-Lan, Taiwan, R.O.C. for the treatment of urinary stones. These urinary stone cases accounted for 50 to 60% of all urology patients admitted. The incidence of urolithiasis in I-Lan was estimated at 147/100,000 population in 1990. There were 402 male patients and 144 female patients, The male to female ratio was 2.8: 1. There were 450 upper urinary tract stones (kidney, ureter) in 314 males and 136 females, and 79 lower urinary tract stones (bladder, urethra) in 72 males and 7 females. The ratio of upper to lower urinary tract stones was 6:1. Endourological treatments such as percutaneous nephrolithotripsy and transurethral ureterolithotripsy have increased rapidly in recent years. A summary of the present analysis for composition of 365 stones follows. The most frequent type was calcium-containing stone (92.3%), followed by infection stone (4.7%), then uric acid (UA) stone (3.0%). There were no UA stones found in the female patients. According to urinalysis criteria of more than 10 WBC/HPF (x 400), pyuria was found in 67 cases of 334 metabolic stones (20.1%), and 11 cases of 17 infection stones (67.7%). There were neither pediatric case of stone formation nor cystine stones. 相似文献

Time trend of incidence of upper urinary tract stone during 15 years was evaluated by hospital-based cohort study in Tajima
area, northern part of Hyogo prefecture, Japan, which has only two general hospitals with Department of Urology. Due to isolation
in terms of traffic network and geographic circumstances, almost all patients with urinary stone in Tajima area are referred
to the two hospitals. During the period 2005–2007, patients of the two hospitals with radiologically proven upper urinary
tract stone were included in this study. The survey included the age and gender, location of stones, history of urinary stone,
treatment received, and stone composition, if available. Annual incidence of upper urinary tract stone was estimated using
the data of population census of Japan 2005 and compared with the data of Tajima during 1991–1993. 1,305 patients were included
in this study. Age-adjusted incidence (±95% CI) was 157 (±22.4) for men, and 57 (±12.6) for women, compared with 141 (±20.7)
for men, and 63 (±13.4) for women during 1991–1993. In total, 30.7% of patients received interventional treatment including
shock wave lithotripsy, endoscopic lithotripsy and open surgery, whereas 25.3% in 1991–1993. Calcium oxalate/phosphate stone
was 89.6%, struvite stone was 4.5%, cystine stone was 1.0%, uric acid stone was 4.0%, and others were 1.0%. In Tajima area,
incidence of upper urinary tract stone has not changed during 15 years. 相似文献

OBJECTIVE: To analyse the impact of stone composition on stone fragility (fragmentation) and clearance of upper urinary tract stones after shock wave lithotripsy (SWL). MATERIAL AND METHODS: Between 1st July 1998 and 31st July 2001, 300 renal and ureteric units of 290 patients (10 being bilateral) underwent SWL for upper urinary tract calculi. The degree of fragmentation was divided into four types: (I) Excellent, (II) Good, (III) Fair and (IV) No fragmentation. Stone composition was done by X-ray diffraction crystallography. A statistical comparison was made between degree of fragmentation, number of shock waves delivered, voltage setting, number of sessions required and requirements of adjuvant procedures according to the stone composition. RESULTS: Stone analysis revealed that 90% of the patients had calcium oxalate stones. Of these 80% were calcium oxalate monohydrate (COM) and 20% calcium oxalate dehydrate (COD). Struvite, apatite and uric acid stones comprised of 6%, 3% and 1% respectively. Type-I fragmentation was achieved up to 63.96%, 50% and 100% in COD, struvite and uric stones respectively as compared to 44.9% and 44.44% for COM and apatite stones. Type-III fragmentation was seen up to 8.79% and 33.3% respectively in COM and apatite as compared to 5.55% or less in other types of the stones suggesting that COM and apatite stones produce larger fragments. The mean number of shock waves, voltage and number of treatments was significantly higher for COM and apatite stones (p value < 0.005) with a stone free rate of only 65-66% and 65-68% respectively at three months (p value < 0.001). Similarly the number of adjuvant procedures required in COM alone was more, i.e. 31 as compared to 17 procedures in rest of the other kinds of stones (p value < 0.05). CONCLUSION: Stone composition in Indian subcontinent is different from the western world. Fragility of a stone varies with the composition of the stone and affects the therapeutic results. 相似文献

Urolithiasis is a common condition in patients with spinal cord injury (SCI). Surgical management of stones in this population is more challenging and associated with lower clearance rates than the general population. The rate of complications – specifically infectious complications – is also high due to the chronic bacterial colonization. Shock wave lithotripsy (SWL) has a low clearance rate of 44–73 %. Percutaneous nephrolithotripsy is indicated for larger nephrolithiasis, but multiple procedures may be required to clear the stones. Ureteroscopy has been associated with low success rates because of difficulty in obtaining ureteral access. Historically, bladder stones were managed with open surgery or SWL. Recently, good results have been reported with the combination of endoscopic and laparoscopic techniques. Surgical management of urolithiasis in patients with SCI should be performed in high-volume centers in light of the technical challenges and higher rate of perioperative complications. 相似文献

Shock wave lithotripsy (SWL) is the gold standard for the treatment of upper urinary tract stones. Despite being relatively non-invasive, SWL can cause renal hematoma (RHT). The aim of this study was to determine incidence and risk factors for RHT following SWL. 857 patients were included in a prospectively maintained database. The observation period spans from 2007 to 2012. 1,324 procedures were performed due to kidney stones. Treatment protocol included power ramping and shock wave frequency of 60–90 per minute as well as an ultrasound check within 3 days of SWL for all patients. Patients with RHT were analyzed, and treatment characteristics were compared with the complete population in a non-statistical manner due to the low event count. RHTs after SWL, sized between 2.6 × 0.6 cm and 17 × 15 cm, were verified in seven patients (0.53 %). In four patients, the RHT was asymptomatic. Three patients developed pain after SWL treatment due to a RHT. In one patient surgical intervention was necessary due to a symptomatic RHT, the kidney was preserved. The risk of RHT following SWL treatment of kidney stones is about 0.5 %. Clinically relevant or symptomatic RHTs occur in 0.23 %, RHTs requiring surgical intervention are extremely rare. Older age and vascular comorbidities appear to be risk factors for the development of RHT. The technical characteristics of SWL treatment and intake of low-dose acetylsalicylic acid due to an imperative cardiologic indication do not appear to influence the risk. Prospective studies are warranted. 相似文献

Health-related quality of life in patients undergoing lithotripsy for urinary stones 总被引:1,自引:0,他引:1

Objectives The objective of this study was to analyze the health-related quality of life (HRQoL) in patients undergoing lithotripsy for
urinary stones.
Materials and methods This study comprised 76 patients with urinary stones who were treated by lithotripsy, which included shock wave lithotripsy
(SWL), ureteroscopic lithotripsy, percutaneous nephrolithotripsy and ureterolithotomy in 66 patients, 25 patients, six patients
and three patients, respectively. During the observation period of this series, 37 patients received additional lithotripsy
for recurrent urinary stones. HRQoL was evaluated using the Short Form-36 (SF-36) survey assessing eight aspects associated
with general health status.
Results There were no significant differences in any scale scores between the 76 patients with urinary stones and age- and gender-matched
Japanese norms. Bodily pain (BP) in 37 patients undergoing lithotripsy twice or more appeared to be significantly lower than
that in 39 undergoing lithotripsy only once; however, there were no significant differences in the remaining seven scores
according to the number of courses of lithotripsy. Furthermore, 47 patients treated by SWL alone had a significantly higher
score for general health perception (GH) than 29 who underwent lithotripsy by methods other than SWL, while there were no
significant differences in the remaining seven scores between these two groups.
Conclusions In general, patients undergoing lithotripsy for urinary stones may have a comparatively favorable HRQoL; however, BP and GH
were impaired in patients undergoing lithotripsy twice or more and those treated by invasive modalities, respectively. Considering
these findings, it would be important to prevent recurrent stone formation and to develop less invasive procedures to further
improve HRQoL in patients undergoing lithotripsy for urinary stones. 相似文献

During the 48-year period from January, 1938 to December, 1985, upper urinary tract stones obtained from 794 patients were analyzed by infrared spectroscopy in our Department. Their clinical manifestations were studied, mainly in relation to stone composition. The ratio of males to females was 3.0 to 1. In recent years, the incidence of females tended to increase. In the age distribution, twenties were most frequent followed by thirties together with fourties before 1965, but after 1966, the thirties were most frequent, and fourties and fifties increased. The composition of 794 stones was as follows. The most frequent type was calcium oxalate combined with calcium phosphate (43.1%), followed by calcium oxalate (39.8%) and calcium phosphate (9.6%). Magnesium ammonium phosphate stones were found in 1.6% and uric acid stones in 2.9%. Calcium oxalate stones, uric acid stones and oxalate-containing stones were found more frequently in males than in females. On the other hand, magnesium ammonium phosphate stones, calcium phosphate stones and phosphate-containing stones were found less frequently in males than in females. There was a high occurrence of calcium phosphate stones and uric acid stones in patients older than 60 years old. The occurrence of calcium oxalate stones and uric acid stones increased and that of phosphate-containing stones decreased after 1966. Most of the recurrent stones revealed the same or similar composition as the initial stones. 相似文献
