OBJECTIVES@#To observe the clinical efficacy of moxibustion combined with western medication on ureteral stent-related symptoms after ureteroscopic lithotripsy (URL).@*METHODS@#One hundred and fifty patients with upper urinary tract calculus implanted with ureteral stents after URL were randomly divided into a moxibustion group (50 cases, 1 case dropped out), a placebo moxibustion group (50 cases, 3 cases dropped out) and a blank control group (50 cases). No intervention was performed in the blank control group. On the basis of oral administration with tamsulosin hydrochloride sustained release capsule (starting from the first day after surgery, once a day, 0.2 mg each time, continuously for 4 weeks), in the moxibustion group, moxibustion was operated at Guanyuan (CV 4) and bilateral Shenshu (BL 23); the sham-moxibustion was delivered at the same acupoints in the placebo moxibustion group, once daily, 6 times a week, for 15 min in each treatment. The duration of treatment was 4 weeks. Before treatment, and after 1, 2 and 4 weeks of treatment, the scores of lower urinary tract symptoms, body pain, general health, work performance and satisfaction of sexual matters were compared among the 3 groups. The tract calculus clearance rate, urinary infection and the oral administration of painkillers were compared after 4 weeks of treatment in the 3 groups.@*RESULTS@#The scores of lower urinary tract symptoms, body pain and general health after 1 week of treatment, and the scores of lower urinary tract symptoms, body pain, general health and work performance after 2 and 4 weeks of treatment were lower than those before treatment in the 3 groups (P<0.01). The scores of lower urinary tract symptoms and body pain in the moxibustion group after 1, 2 and 4 weeks of treatment were lower than those in the blank control group and the placebo moxibustion group (P<0.01, P<0.05) respectively. The score of general health in the moxibustion group was lower than that in the blank control group after 1 week of treatment (P<0.01), and lower than those of the blank control group and the placebo moxibustion group after 2 and 4 weeks of treatment (P<0.01, P<0.05). Regarding the score of work performance, it was lower in the moxibustion group after 1 and 2 weeks of treatment compared with those in the blank control group (P<0.05, P<0.01), and lower than those of the blank control group and the placebo moxibustion group after 4 weeks of treatment (P<0.01, P<0.05). The tract calculus clearance rate in the moxibustion group was 95.9% (47/49), higher than that in the blank control group (80.0%, 40/50, P<0.05). The proportion of oral administration of painkillers in the moxibustion group (28.6%, 14/49) and the placebo moxibustion group (40.4%, 19/47) was lower than that in the blank control group (76.0%, 38/50, P<0.01) respectively.@*CONCLUSIONS@#Moxibustion combined with western medication relieves lower urinary tract symptoms and body pain, and accelerate the recovery of general health and work performance in the patients after URL.

La segunda parte del Consenso Argentino Intersociedades de Infección Urinaria incluye el análisis de situaciones especiales. En pacientes con sonda vesical se debe solicitar urocultivo solo cuando hay signo-sintomatología de infección del tracto urinario, antes de instrumentaciones de la vía urinaria o como control en pacientes post-trasplante renal. El tratamiento empírico recomendado en pacientes sin factores de riesgo es cefalosporinas de tercera generación o aminoglucósidos. Las infecciones del tracto urinario asociadas a cálculos son siempre consideradas complicadas. En caso de obstrucción con urosepsis, deberá realizarse drenaje de urgencia por vía percutánea o ureteral. En pacientes con stents o prótesis ureterales, como catéteres doble J, el tratamiento empírico deberá basarse en la epidemiología, los antibióticos previos y el estado clínico. Antes del procedimiento de litotricia extracorpórea se recomienda pesquisar la bacteriuria y, si es positiva, administrar profilaxis antibiótica según el antibiograma. Cefalosporinas de primera generación o aminoglúcosidos son opciones válidas. Se recomienda aplicar profilaxis antibiótica con cefalosporinas de primera generación o aminoglúcosidos antes de la nefrolitotomía percutánea. La biopsia prostática trans-rectal puede asociarse a complicaciones infecciosas, como infecciones del tracto urinario o prostatitis aguda, principalmente por Escherichia coli u otras enterobacterias. En pacientes sin factores de riesgo para gérmenes multirresistentes y urocultivo negativo se recomienda realizar profilaxis con amikacina o ceftriaxona endovenosas. En pacientes con urocultivo positivo, se realizará profilaxis según antibiograma, 24 horas previas a 24 horas post-procedimiento. Para el tratamiento dirigido de la prostatitis post-biopsia trans-rectal, los carbapenémicos durante 3-4 semanas son el tratamiento de elección.
The second part of the Inter-Society Argentine Consensus on Urinary Tract Infection (UTI) includes the analysis of special situations. In patients with urinary catheter, urine culture should be requested only in the presence of UTI symptomatology, before instrumentation of the urinary tract, or as a post-transplant control. The antibiotics recommended for empirical treatment in patients without risk factors are third-generation cephalosporins or aminoglycosides. UTIs associated with stones are always considered complicated. In case of obstruction with urosepsis, an emergency drainage should be performed via a percutaneous nefrostomy or ureteral stenting. In patients with stents or ureteral prostheses, such as double J catheters, empirical treatment should be based on epidemiology, prior antibiotics, and clinical status. Before the extracorporeal lithotripsy procedure, bacteriuria should be investigated and antibiotic prophylaxis should be administered in case of positive result, according to the antibiogram. First generation cephalosporins or aminoglycosides are valid alternatives. The use of antibiotic prophylaxis with first-generation cephalosporins or aminoglycosides before percutaneous nephrolithotomy is recommended. Transrectal prostatic biopsy can be associated with infectious complications, such as UTI or acute prostatitis, mainly due to Escherichia coli or other enterobacteria. In patients without risk factors for multiresistant bacteria and negative urine culture, prophylaxis with intravenous amikacin or ceftriaxone is recommended. In patients with positive urine culture, prophylaxis will be performed according to the antibiogram, from 24 hours before to 24 hours post-procedure. For the targeted treatment of post-transrectal biopsy prostatitis, carbapenems for 3-4 weeks are the treatment of choice.

Resumen: La litotricia extracorpórea por ondas de choque para el tratamiento de la urolitiasis es un tratamiento ampliamente aceptado, pero no exento de complicaciones. La pancreatitis aguda que se desencadena inmediatamente posterior a este procedimiento es infrecuente, pero puede ser una complicación grave que amenaza la vida del paciente. La aparición aguda de dolor abdominal y vómitos en las horas posteriores al procedimiento, deben hacer al médico tratante sospechar esta complicación. Presentamos el caso de un paciente joven que luego de someterse a una sesión de litotricia para el tratamiento de una litiasis renal derecha instaló una pancreatitis aguda que requirió ingreso a terapia intensiva y que se suma a los escasos informes de casos publicados en la literatura médica.
Summary: Extracorporeal shock wave lithotripsy to treat urolithiasis is a widely aceptable treatment, although it may involve complications. Acute pancreatitis immediately after the procedures is rather unusual, but it may result in a serious life-threatening complication for patients. The appearance of severe pain and vomits a few hours after the procedure should make physicians suspicious of this complication. The study presents the case of a young patient who developed acute pancreatitis after undergoing lithotripsy to treat lithiasis in the right kidney, requiring his admission to the intensive care unit. This will add up to the scarce reports published in the medical literature.
Resumo: A litotrícia extracorpórea por ondas de choque para o tratamento da urolitíase é um tratamento amplamente aceito, mas não isento de complicações. A pancreatite aguda que se desencadeia imediatamente depois deste procedimento não é frequente, porém pode ser uma complicação grave que ameaça a vida do paciente. O surgimento súbito de dor abdominal e vómitos nas horas seguintes ao procedimento devem induzir à suspeita desta complicação. Apresentamos o caso de um paciente jovem que depois de uma sessão de litotrícia para o tratamento de uma litíase renal direita apresentou uma pancreatite aguda com posterior admissão a terapia intensiva; este caso se agrega aos poucos publicados na literatura médica.

ABSTRACT Background Shock wave lithotripsy (SWL) is the first line treatment modality for a significant proportion of patients with upper urinary tracts stones. Simple analgesics, opioids and non-steroidal anti-inflammatory drugs (NSAIDs) are all suitable agents but the relative efficacy and tolerability of these agents is uncertain. Objectives To determine the efficacy of the different types of analgesics used for the control of pain during SWL for urinary stones. Materials and Methods We searched the Cochrane Renal Group’s Specialised Register, MEDLINE, EMBASE and also hand-searched reference lists of relevant articles (Figure-1). Randomised controlled trials (RCT’s) comparing the use of any opioid, simple analgesic or NSAID during SWL were included. These were compared with themselves, each-other or placebo. We included any route or form of administration (bolus, PCA). We excluded agents that were used for their sedative qualities. Data were extracted and assessed for quality independently by three reviewers. Meta-analyses have been performed where possible. When not possible, descriptive analyses of variables were performed. Dichotomous outcomes are reported as relative risk (RR) and measurements on continuous scales are reported as weighted mean differences (WMD) with 95% confidence intervals. Results Overall, we included 9 RCTs (539 participants from 6 countries). Trial agents included 7 types of NSAIDs, 1 simple analgesic and 4 types of opioids. There were no significant differences in clinical efficacy or tolerability between a simple analgesic (paracetamol) and an NSAID (lornoxicam). When comparing the same simple analgesic with an opioid (tramadol), both agents provided safe and effective analgesia for the purpose of SWL with no significant differences. There were no significant differences in pain scores between NSAIDs or opioids in three studies. Adequate analgesia could be achieved more often for opioids than for NSAIDs (RR 0.358; 95% CI 043 to 0.77, P=0.0002) but consumed doses of rescue analgesia were similar between NSAIDs and opioids in two studies (P=0.58, >0.05). In terms of tolerability, there is no difference in post-operative nausea and vomiting (PONV) between the groups (RR 0.72, 95% CI 0.24 to 2.17, P=0.55). One study compared outcomes between two types of NSAIDs (diclofenac versus dexketoprofen). There were no significant differences in any of our pre-defined outcomes measures. Conclusion Simple analgesics, NSAIDs and opioids can all reduce the pain associated with shock wave lithotripsy to a level where the procedure is tolerated. Whilst there are no compelling differences in safety or efficacy of simple analgesics and NSAIDs, analgesia is described as adequate more often for opioids than NSAIDs.

ABSTRACT Background: We analyzed the outcome and complications of rigid (R-URS) and flexible (F-URS) ureteroscopic lithotripsy for treatment of proximal ureteric stone (PUS). Subjects and methods: Retrospective data of 135 patients (93 males and 42 females) submitted to R-URS and F-URS for treatment of PUS in the period between July 2013 and January 2015 were investigated. (R-URS, group 1) was performed in 72 patients while 63 patients underwent (F-URS, group 2).We compared the 2 groups for success, stone characteristics, operative time, intraoperative and postoperative complications. Results: The overall stone free rate (SFRs) was 49/72 (68%) in group 1 and 57/63 (91%) patients in group 2, (P=0.005). The operative time was shorter in group 1 in comparison to group 2 with statistically significant difference (P=0.005). There was not any statistically significant difference between 2 groups in complication rate (P=0.2). Conclusıon: Both R-URS and F-URS could be a feasible option for treatment of PUS. R-URS is less successful for treatment of PUS and should be used cautiously and with availability of F-URS.

This study aimed to evaluate the effect of preoperative imaging techniques on the success and complication rates of ureteroscopy. We performed a retrospective analysis of 736 patients (455 males and 281 females), with a mean age of 45.5±15.2 years (range, 1-88 years), who underwent rigid ureteroscopic procedures for removal of ureteral stones. Patients were divided into 4 groups according to the type of imaging modality used: group I, intravenous urography (n=116); group II, computed tomography (n=381); group III, computed tomography and intravenous urography (n=91), and group IV, ultrasonography and abdominal plain film (n=148). Patients’ demographics, stone size and location, prior shock wave lithotripsy, lithotripsy technique, operation time, success rate, and rate of intraoperative complications were compared among the groups. There were no significant differences in success and complication rates among the groups. The stone-free rate after primary ureteroscopy was 87.1% in group I, 88.2% in group II, 96.7% in group III, and 89.9% in group IV (P=0.093). The overall incidence of intraoperative complications was 11.8%. According to the modified Satava classification system, 6.1% of patients had grade 1, 5.1% had grade 2, and 0.54% had grade 3 complications. Intraoperative complications developed in 12.1% of patients in group I, 12.6% of patients in group II, 7.7% of patients in group III, and 12.2% of patients in group IV (P=0.625). Our findings clearly demonstrate that ureteroscopic treatment of ureteral stones can be safely and effectively performed with no use of contrast study imaging, except in doubtful cases of anatomical abnormalities.

The use of certain technical principles and the selection of favorable cases can optimize the results of extracorporeal shock wave lithotripsy (ESWL). The aim of this study is to review how ESWL works, its indications and contraindications, predictive factors for success, and its complications. A search was conducted on the Pubmed® database between January 1984 and October 2013 using "shock wave lithotripsy" and "stone" as key-words. Only articles with a high level of evidence, in English, and conducted in humans, such as clinical trials or review/meta-analysis, were included. To optimize the search for the ESWL results, several technical factors including type of lithotripsy device, energy and frequency of pulses, coupling of the patient to the lithotriptor, location of the calculus, and type of anesthesia should be taken into consideration. Other factors related to the patient, stone size and density, skin to stone distance, anatomy of the excretory path, and kidney anomalies are also important. Antibiotic prophylaxis is not necessary, and routine double J stent placement before the procedure is not routinely recommended. Alpha-blockers, particularly tamsulosin, are useful for stones >10mm. Minor complications may occur following ESWL, which generally respond well to clinical interventions. The relationship between ESWL and hypertension/diabetes is not well established.
A utilização de certos princípios técnicos e a seleção de casos favoráveis podem otimizar os resultados da litotripsia extracorpórea por ondas de choques (LECO). O objetivo deste trabalho é revisar os princípios de funcionamento da LECO, suas indicações e contraindicações, fatores preditivos de sucesso e suas complicações. Realizou-se uma pesquisa na base de dados do Pubmed® entre janeiro/1984 e outubro/2013 utilizando como palavras chaves shock wave lithotripsy e stone. Apenas artigos com bom nível de evidência, de língua inglesa, em seres humanos, do tipo clinical trials ou de revisão/metanálise foram incluídos. Na busca pela otimização dos resultados da LECO, diversos fatores técnicos, como o tipo de aparelho de litotripsia, energia e frequência dos pulsos, acoplamento do paciente ao litotridor, localização do cálculo e tipo de anestesia, devem ser levados em consideração. Fatores relacionados ao doente e ao cálculo, como seu tamanho, densidade, distância pele-cálculo, anatomia da via excretora e anomalias renais, também são importantes. A profilaxia com antibiótico não é necessária, e a passagem de duplo J de rotina não é recomendada. A prescrição de alfabloqueadores, particularmente a tansulosina, é benéfica em cálculos > 10 mm. Complicações menores podem ocorrer após LECO e geralmente respondem bem a condutas clínicas. A relação entre LECO e o surgimento de hipertensão e diabetes não está comprovada.

Objective The aim of this study was to evaluate the capability and the reliability of diffusion-weighted imaging (DWI) in the changes of kidneys occurring after extracorporeal shock wave lithotripsy (ESWL) treatment for renal stones. Materials and Methods A total of 32 patients who underwent ESWL treatment for renal stone disease between June and December 2011 were enrolled in this prospective study. Color Doppler ultrasonography (CDUS) and DWI were performed before and within 24 hours after ESWL. DWI was obtained with b factors of 0, 500 and 1000 s/mm2 at 1.5 T MRI. Each of Resistive index (RI) and ADC values were calculated from the three regions of renal upper, middle and lower zones for both of the affected and contralateral kidneys. Paired sample t test was used for statistical analyses. Results After ESWL, the treated kidneys had statistically significant lower ADC values in all different regions compared with previous renal images. The best discriminative parameter was signal intensity with a b value of 1000 s/mm2. The changes of DWI after ESWL were noteworthy in the middle of the treated kidney (p<0.01). There were no significant difference between RI values in all regions of treated and contralateral kidneys before and after treatment with ESWL (p>0.05). Conclusion DWI is a valuable technique enables the detection of changes in DWI after ESWL treatment that may provide useful information in prediction of renal damage by shock waves, even CDUS is normal. .

BACKGROUND/AIMS: Various anatomical features of the biliary tree affect ability to remove difficult common bile duct (CBD) stones. In this study, we evaluated the clinical characteristics and outcomes of the endoscopic treatment of stones in stemware-shaped CBDs. METHODS: Thirty-four patients with a stone and a stemware-shaped CBD who were treated at different tertiary referral centers from January 2008 to December 2012 were studied retrospectively. When stone removal failed, percutaneous or direct peroral cholangioscopic lithotripsy, endoscopic retrograde biliary drainage, or surgery was performed as a second-line procedure. RESULTS: The overall success rate of the first-line procedure was 41.2%. Five of the 34 patients (14.7%) experienced procedure-related complications. No procedure-related mortality occurred. Mechanical lithotripsy was required to completely remove stones in 13 patients (38.2%). Conversion to a second-line procedure was required in 20 patients (58.8%). Mechanical lithotripsy was needed in 75% and 66.7% of those with a stone size of or =1 cm, respectively. Stone recurrence occurred in two patients (9.1%) after 6 months and 27 months, respectively. CONCLUSIONS: The endoscopic treatment of stones in a stemware-shaped CBD is challenging. The careful assessment of difficult CBD stones is required before endoscopic procedures.

PURPOSE: To evaluate the efficacy, safety and patient satisfaction outcomes following low intensity extracorporeal shock wave therapy (LiESWT) in men with Peyronie's disease (PD) using a standardised protocol. MATERIALS AND METHODS: In this open-label single arm prospective study, patients with PD were enrolled following informed consent. Patient demographics, change in penile curvature and plaque hardness, International Index of Erectile Function (IIEF)-5 score, and overall satisfaction score (on a 5-point scale) were recorded. Treatment template consists of 3000 shock waves to the Peyronie's plaque over 20 minutes, twice weekly for 6 weeks. RESULTS: The majority of patients have PD history longer than 6 months (mean, 12.8 months; range, 6-28 months). Two thirds of patients have received and failed oral medical therapy. There were improvements in penile curvature (more than 15 degrees in 33% of men), plaque hardness (60% of men) and penile pain (4 out of 6 men) following LiESWT. There was a moderate improvement in IIEF-5 score (>5 points reported in 20% of men). No complication was reported and the majority of patients were satisfied (rated 4 out of 5; 70% of men) and would recommend this therapy to others. CONCLUSIONS: In a carefully selected group of men with PD, LiESWT appears to be safe, has moderate efficacy and is associated with high patient satisfaction rate in the short term.

When access to a major duodenal papilla or endoscopic retrograde cholangiopancreatography has failed, percutaneous transhepatic cholangioscopic lithotripsy (PTCS-L) may be useful for removing common bile duct (CBD) stones. However, the feasibility and usefulness of percutaneous transhepatic papillary large-balloon dilation (PPLBD) during PTCS-L for the removal of large CBD stones has not been established. We aimed to determine the safety and efficacy of PPLBD for the treatment of large CBD stones. Eleven patients with large CBD stones in whom the access to the major papilla or bile duct had failed were enrolled prospectively. Papillary dilation was performed using a large (12-20 mm) dilation balloon catheter via the percutaneous transhepatic route. Post-procedure adverse events and efficacy of the stone retrieval were measured. The initial success rate of PPLBD was 100%. No patient required a basket to remove a stone after PPLBD. Electrohydraulic lithotripsy was required in 2 (18.2%) patients. The median time to complete stone removal after PPLBD was 17.8 min and no adverse events occurred after PPLBD. Asymptomatic hyperamylasemia was not encountered in any patients. This study indicates that PPLBD is safe and effective for removal of large CBD stones.

Severe skin injury after extracorporeal shock wave lithotripsy (ESWL) is rare. We describe two patients who suffered full thickness skin burns following ESWL for renal calculi. One patient was treated conservatively and the other underwent debridement with skin grafting. We speculate that failure of the thermostatic mechanism of the lithotripter, leading to overheating of the water-filled cushion, resulted in this very rare adverse event. Proper preoperative patient counseling regarding the risk of serious burn injuries will help to avoid potential litigation.

Purpose We investigated the characteristics and management of patients with intravenous misplacement of a nephrostomy tube. Materials and Methods Between July 2007 and July 2013, 4148 patients with urolithiasis underwent percutaneous nephrolithotomy (PCNL) in our hospital. Intravenous misplacement of a nephrostomy tube occurred in two of these patients. Another patient with intravenous misplacement of a nephrostomy tube, who underwent PCNL in another hospital, was transferred to our hospital. The data of the three patients were retrospectively analyzed. Results The incidence of intravenous misplacement of a nephrostomy tube following PCNL was 0.5% (2/4148) at our hospital. A solitary kidney was present in one of the three patients. The tip of tube was located into the inferior vena cava (IVC) in two patients and into the renal vein in one patient. All three patients were successfully managed with strict bed rest, intravenous antibiotics and one-step (one patient) or two-step (two patients) tube withdrawal under close monitoring. None of the patients underwent antithrombotic therapy. The original operations were performed successfully under close observation in two patients and changed to another operation in one patient. All patients were discharged uneventfully. Conclusions The incidence of intravenous misplacement of a nephrostomy tube following PCNL is 0.5% at our hospital. Intravenous nephrostomy tube misplacement is an uncommon complication of PCNL. A solitary kidney may render patients susceptible to this complication. Most patients may be managed conservatively with strict bed rest, intravenous antibiotics and one-step or two-step tube withdrawal under close monitoring. .

The treatment for patients with large impacted proximal ureteral stone remains controversial, especially at institutions with limited resources. The aim of this study is to compare and to evaluate the outcome and complications of two main treatment procedures for impacted proximal ureteral calculi, retrograde ureterolithotripsy [URS], and percutaneous antegrade ureterolithotripsy [Perc-URS]. Our inclusion criteria were solitary, radiopaque calculi, >15 mm in size in a functioning renal unit. Only those patients in whom the attempt at passing a guidewire or catheter beyond the calculus failed were included in this study. Between January 2007 and July 2011, a total of 52 patients [13 women and 39 men] with large impacted upper-ureteral calculi >15 mm and meeting the inclusion criteria were selected. Of these, Perc-URS was done in 22 patients [group 1] while retrograde ureteroscopy was performed in 30 patients [group 2]. We analyzed operative time, incidence of complications during and after surgery, the number of postoperative recovery days, median total costs associated per patient per procedure, and the stone-free rate immediately after 5 days and after 1 month. Bivariate analysis used the Student t-test and the Mann-Whitney test to compare two means and Chi-square and Fisher's exact tests to compare two percentages. The significance level was set at 0.05. The mean age was 42.3 years [range 22-69]. The mean stone sizes [mm] were 34 +/- 1.2 and 29.3 +/- 1.8 mm in group 1 and 2, respectively. In the Perc-URS group, 21 patients [95.45%] had complete calculus clearance through a single tract in one session of percutaneous surgery, whereas in the URS group, only 20 patients [66.7%] had complete stone clearance [P = 0.007]. The mean operative time was higher in the Perc-URS group compared to group 2 [66.5 +/- 21.7 vs. 52.13 +/- 17.3 min, respectively; P = 0.013]. Complications encountered in group 1 included transient postoperative fever [2 pts] and simple urine outflow [2 pts]. Ten patients [33%] of group 2 experienced failure: Migration to the kidney [3 pts], ureteral perforation [2 pts], tortuosity of the ureter [2 pts], and epithelial polyps [2 patients]. Group 1 patients had an average visual analog [VAS] pain score of 47 mm compared with 31 mm in group 2 patients. The mean hospital stay [days] in group 1 was higher than the group 2 [2.27 +/- 0.8 vs. 1.67 +/- 0.6, respectively; P = 0.01]. The mean analgesia requirement for group 1 [paracetamol chlorhydrate + codeine 12 +/- 3 g] was significantly more compared with group B [6.8 +/- 2 g] [P < 0.01]. The difference in average blood loss between the two groups was not statistically significant. Total costs was slightly higher in group 1 but the difference was not statistically significant between the two groups [15000 vs. 13400 MDH respectively; P > 0.05]. After 1 month, the stone free-rate remained higher in group 1 [95.5% vs. 66.7%, respectively; P = 0.012]. In our series, Perc-URS is a safe and efficient treatment option for proximal ureteral stone, especially when the stone size is superior to 15 mm with the presence of moderate or severe hydronephrosis.

To compare the efficacy of ureteroscopic pneumatic lithotripsy [URS] and extracorporeal shock wave lithotripsy [ESWL] in the treatment of lower ureteric stones in terms of stone-free rates. Randomized trial. Department of Urology, Government Institute of Kidney Diseases and Transplant, Hayatabad, Peshawar, from September 2010 to March 2011. Patients [n=136] presented with lower ureteric stones and fulfilling the inclusion criteria for the study were included. They were divided equally into two groups. Division of patients was done by lottery method. Patients in group A were treated with ureteroscopic pneumatic lithotripsy [URS] as compared to those in group B, who were dealt with extracorporeal shock wave lithotripsy [ESWL]. There were 46 males [67.6%] and 22 females [32.3%] with a ratio of 2.1:1 in group A as compared to 50 males [72%] and 18 females [26.4%] with a ratio of 2.8:1 in group B. Mean age was 35.2 +/- 9.5 years in group A and 35.4 +/- 9.2 years in group B. The mean stone size in group A was 12.8 +/- 3.7 [range 5 - 25 mm] and 12.82 +/- 3.5 [range 5 - 25 mm] in group B. Mean hospital stay in group A was 2.07 +/- 0.6, while patients in group B were all day-cases. The statistical difference was significant in terms of repeat procedure, auxiliary procedure postoperative analgesia and stone free status at 3 months [p=0.043, 0.020, 0.000, 0.001] respectively, while it was not significant in respect of complications of procedure [p=0.753]. URS proved more effective than ESWL for the treatment of ureteric calculi. However, ESWL performed as an outpatient procedure showed fewer complications

Afferent loop syndrome is a rare complication which can occur in patients with Billroth II gastrectomy. Bile and pancreatic juice is congested at afferent loop in the syndrome. This syndrome can progress rapidly to necrosis, perforation, or severe sepsis, and therefore early diagnosis and swift surgical intervention is important. But, cases of endoscopic or percutaneous transhepatic drainage have been reported when surgical management was inappropriate to proceed. We report a case of afferent loop syndrome accompanying acute cholangitis developed after percutaneous transhepatic cholangioscopic lithotripsy for the retrieval of common bile duct stone in a patient who underwent Billroth II gastrectomy due to early gastric cancer. There was no other organic cause. We treated afferent loop syndrome successfully by performing balloon dilation of afferent loop outlet.

Subcapsular and perinephric hematomas are relatively common after shock-wave lithotripsy, but high-grade kidney injuries are extremely rare. We present the first case of a high-grade kidney injury after shock-wave lithotripsy managed conservatively. A 57-year-old white female patient with left 1.5cm superior ureteral calculi was submitted to shock-wave lithotripsy.

PURPOSE: Urinary stone disease is a common medical problem. Extracorporeal shockwave lithotripsy (SWL) has been applied with high success and low complication rates. Steinstrasse (SS) is a possible complication after SWL. The aim of the present study was to prospectively evaluate the factors and outcomes associated with SS after SWL. MATERIALS AND METHODS: We have prospectively evaluated 265 SWL sessions (2005-2009). Two lithotriptors were used randomly: Siemens Lithostar and Dornier Compact S. All patients had imaging exams after 30 and 90 days or according to symptoms. RESULTS: SS was observed in 14 (5.3 percent) out of 265 SWL procedures (n = 175 patients, 51.5 percent women/48.5 percent men, mean ± SD age = 46.3 ± 15.5 years). SS was more common after SWL for pelviureteral calculi rather than caliceal stones (p = 0.036). There was a trend toward more occurrences of SS after SWL for larger stone area (> 200 mm², p = 0.072). Preoperative ureteral stent didn't prevent SS. SWL machine, intensity, number of pulses and frequency were not associated with SS formation. Post-SWL pain, fever and gravel elimination were factors associated with SS (p = 0.021; p = 0.011; p = 0.078). When SS occurred, treatment modalities included Medical Expulsive Therapy (MET), ureteroscopy and SWL. CONCLUSIONS: Steinstrasse is an uncommon event after SWL and seems to occur more frequently with larger pelviureteral stones. Impaction of stones is more frequent in the middle ureter. All patients should be followed after SWL, but SS should be specially suspected if there is macroscopic gravel elimination, flank pain and/or fever. When SS occurs, treatment should be promptly introduced, including medical expulsive therapy, surgical approach or SWL in selected cases. Further prospective studies are awaited to evaluated preventive measures for SS occurrence.
