RESUMO
OBJECTIVE: To evaluate the time interval and possible delay in transportation to referral units for the treatment of testicular torsion. METHODS: We retrospectively analyzed all cases of spermatic cord torsion surgically treated at a university hospital between January 2018 to December 2021. We evaluated the time intervals, including pain onset until the first presentation (D1), interhospital transference time (D2), pain onset until urological evaluation in a tertiary service (D3), urological evaluation until surgery (D4), and time from pain onset to surgical treatment (D5). We analyzed demographic and surgical data, orchiectomy rates, and time intervals (D1-D5). Torsions presented to the first medical presentation within 6h were considered early for testicular preservation. RESULTS: Of the 116 medical records evaluated, 87 had complete data for the time interval analysis (D1 to D5) and were considered the total sample. Thirty-three had D1 ≤6h, 53 had D1 ≤24h (includes patients in the D1 ≤6h subgroup), and 34 had D1 >24h. The median time intervals of the total samples and subgroups D1 ≤6h, D1 ≤24h, and D1 >24h were D1 = 16h 42min, 2h 43min, 4h 14min and 72h, D2 = 4h 41min, 3h 39min, 3h 44min and 9h 59min; D3 = 24h, 6h 40min, 7h and 96h; D4 = 2h 20min, 1h 43min, 1h 52min and 3h 44min; D5 = 24h 42min, 8h 03min, 9h 26min and 99h 10min, respectively. Orchiectomy rates of the total sample, subgroups D1 ≤6h, D1 ≤24h, and D1 >24h were 56.32%, 24.24% (p<0.01), 32.08% (p<0.01), and 91.18% (p<0.01), respectively. CONCLUSION: Late arrival at the emergency department or a long interhospital transference time determined a large number of patients who underwent orchiectomy. Thus, public health measures and preventive strategies can be developed based on the data from this study aiming to reduce this avoidable outcome.

PURPOSE: The best treatment modalities for large proximal ureteral stones are controversial, and include extracorporeal shock wave lithotripsy, ureterolithotripsy, percutaneous nephrolithotripsy, laparoscopic ureterolithotomy and open surgery. To the best of our knowledge extracorporeal shock wave lithotripsy, semirigid ureterolithotripsy and laparoscopic ureterolithotomy have not been previously compared for the treatment of large proximal ureteral stones. Therefore, we compared these modalities for the treatment of large proximal ureteral stones. MATERIALS AND METHODS: A total of 48 patients with large proximal ureteral stones (greater than 1 cm) were prospectively randomized and enrolled in the study at a single institution between 2008 and 2010. Eligible patients were assigned to extracorporeal shock wave lithotripsy, semirigid ureterolithotripsy or laparoscopic ureterolithotomy. RESULTS: Extracorporeal shock wave lithotripsy had a 35.7% success rate, semirigid ureterolithotripsy 62.5% and laparoscopic ureterolithotomy 93.3%. Stone-free rates showed a statistically significant difference among the groups (p = 0.005). Patients treated with laparoscopic ureterolithotomy vs semirigid ureterolithotripsy vs extracorporeal shock wave lithotripsy required fewer treatment sessions (mean ± SD 1.9 ± 0.3 vs 2.2 ± 0.6 vs 2.9 ± 1.4, p = 0.027). Neither major nor long-term complications were observed. CONCLUSIONS: Proximal ureteral stone treatment requires multiple procedures until complete stone-free status is achieved. Laparoscopic ureterolithotomy is associated with higher success rates and fewer surgical procedures, but with more postoperative pain, longer procedures and a longer hospital stay. Although it is associated with the highest success rates for large proximal ureteral calculi, laparoscopic ureterolithotomy remains a salvage, second line procedure, and it seems more advantageous than open ureterolithotomy. At less well equipped centers, where semirigid ureterolithotripsy or extracorporeal shock wave lithotripsy is not available, it remains a good treatment option.

We describe the case of a female patient with calcification in renal topography, initially diagnosed as lithiasis in the left kidney, and later attributed to calcification of intrarenal vascular aneurysm. Next, we discuss the relevance of considering such an entity in the differential diagnoses of intrarenal calcifications before choosing any form of specific interventional treatment.

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%) out of 265 SWL procedures (n = 175 patients, 51.5% women/48.5% 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.

ABSTRACT Introduction: It has been more than a year since the first case of Covid-19 was diagnosed in Brazil, and its most problematic feature is the oversaturation of the healthcare system capacity. Urolithiasis is a disease that requires timely and appropriate management. The present study aimed to evaluate the impact of the pandemic in hospital admissions for urolithiasis in the Brazilian public healthcare system. Materials and Methods: In this cross-sectional study, hospital admissions were obtained from the Brazilian Public Health Information system. All hospital admissions associated with urolithiasis diagnosis (ICD-10 N20) between March 2017 and February 2021 were analyzed. Results: During the COVID-19 outbreak, there was a significant decrease in hospital admissions (p<0.0001). More than 20.000 patients probably did not have the opportunity to undergo their surgeries. The impact of the COVID-19 outbreak on women's admissions was significantly more intense than for men, reducing from 48.91% to 48.36% of the total (p=0.0281). The extremes of age seemed to be more affected, with patients younger than 20 years and older than 60 years having a significant reduction in access to hospital services (p=0.033). Conclusions: In conclusion, we have noticed a considerable reduction in overall admissions for the treatment of urolithiasis in the Brazilian public healthcare system during the first year of the Covid-19 pandemic. Women and individuals older than 60 years were especially affected. In contrast, we noted a rise in urgent procedures, comparing with the average of the corresponding period of the three previous years. Recovery plans will be needed while returning to activities to handle the impounded surgical volume.

Giant prostatic hyperplasia is a rare condition characterized by very high volume benign prostatic enlargement (>500g). Few cases have been reported so far and most of them are associated with severe lower urinary symptoms. We report the first case of asymptomatic giant prostatic hyperplasia in an elderly man who had a 720g prostate adenoma, sudden gross hematuria and hypovolemic shock. The patient was successfully treated with open transvesical prostatectomy and had an uneventful postoperative recovery.

Considering the Health Care System in Brazil, a developing country, and public healthcare policies, robotic surgery is a reality to very few citizens. Therefore, robotic assisted radical prostatectomy is far removed from the daily practice of the vast majority of Brazilian urologists. Scientific evidence of the superiority of robotic assisted radical prostatectomy does not presently justify public investments for widespread development of robotic centers. Maybe over time and with reductions in costs, robotic technology will become a more established practice, as observed in other countries, and more feasible for the Brazilian urological community.

A hiperplasia prostática gigante é uma condição rara caracterizada por aumento benigno prostático significativo, com volume maior que 500g. Existem poucos casos relatados e, em sua maioria deles está associada a sintomas graves do trato urinário inferior. Relatamos aqui o primeiro caso de hiperplasia prostática benigna assintomática em paciente idoso com próstata de 720g, hematúria macroscópica de início súbito e choque hipovolêmico. O paciente foi submetido com sucesso à prostatectomia suprapúbica, sem intercorrências no intra e pós-operatório.

Percutaneous access to the kidney has gained widespread use during the last decades. Iatrogenic colon injury is an uncommon but serious complication. Diagnosis is sometimes delayed, and treatment strategies are still controversial, including conservative management, colostomy, or primary repair. The aim of this review is to identify optimal diagnostic and treatment options for such injuries.

OBJECTIVE: To present a previously unreported long term complication of percutaneous nephrolithotomy for exclusive renal stone. METHODS/RESULTS: A 30-years-old woman underwent percutaneous nephrolithotomy for a obstructive pelvic stone, through inferior calix access achieving a stone free status. During the procedure occurred an inadvertent pelvis perforation, but the early evolution was otherwise uneventful. Patient was asymptomatic during the follow-up. However, a urinary ultrasound disclosed important pielocalyceal dilation, and further investigation demonstrated extensive proximal ureteral stricture. CONCLUSION: Ureteral stricture may rarely occur as a late complication of percutaneous nephrolithotomy. A review of the literature of this quite uncommon complication was performed and the authors discuss the possible etiology and preventive measures.

OBJECTIVE: Vesical perforation during transurethral resection of the prostate (TURP) is usually related to high increases in intravesical pressure. However, it may rarely be related to explosion precipitated by the contact of the electrocautery with some gases produced during the resections. The authors present a case of vesical explosion, discuss its mechanism and suggest some measures for prevention. METHODS/RESULTS: A 71-years-old male underwent TURP and hemostasy of bleeding from the bladder neck due to persistent hematuria. A wire loop electrode set at a cutting and coagulating current of 80 watts was used. During coagulation of a bleeding in the anterior aspect of the vesical neck when the bladder was empty, a loud pop was heard and a jolt was felt at the lower abdomen. Inspection revealed a hole in the dome of the bladder with loops of small bowel visible. A low midline incision was done, and the intraperitoneal bladder rupture was repaired. CONCLUSION: Although uncommon, vesical explosion during TURP may occur and some preventive measures, discussed herein, can be performed to avoid this complication.

Levando em conta o Sistema de Saúde do Brasil, um país em desenvolvimento, e as políticas de saúde pública, a cirurgia robótica é uma realidade disponível a poucos cidadãos. Assim, a prostatectomia radical robô-assistida está longe da prática diária da grande maioria dos urologistas brasileiros. As evidências científicas da superioridade da prostatectomia radical assistida por robôs não justificam, no momento, os investimentos públicos para o desenvolvimento disseminado de centros de robótica. Talvez mais tarde e com redução nos custos, a tecnologia da robótica torne-se uma prática mais estabelecida, como já observado em outros países, e fique, assim, mais viável para a comunidade urológica do Brasil.
RESUMO
Objetivos: Demonstrar a experiência e os resultados em nefrolitotripsia percutânea na Faculdade de Medicina do ABC. Pacientes e métodos: Entre janeiro de 2002 e janeiro de 2005, foram revisados os prontuários de 69 pacientes foram submetidos a NLPC. Resultados: A massa calcárea média foi de 850 mm2. Todos os pacientes foram tratados através de apenas uma punção renal e somente em 1 caso foi necessária transfusão peri-operatória. A taxa de sucesso após o procedimento inicial foi de 70%, sendo 39% livre de cálculo. Após tratamentos complementares a taxa de sucesso final foi de 85,5%. Conclusão: Os nossos resultados iniciais em NLPC foram um pouco inferiores aos publicados em outras séries. Tal diferença pode ser justificada pela curva de aprendizado inicial neste procedimento, envolvimento de residentes em treinamento, pelo maior volume dos cálculos em relação aos trabalhos da literatura, por ter sido realizada apenas uma punção e não disponibilidade de material flexível para exploração completa da via excretora.

A litíase ureteral é uma afecção freqüente e que pode acarretar doloroso quadro de cólica renal. Quando existe necessidade de intervenção, várias opções podem ser cogitadas. O surgimento de técnicas endourológicas e procedimentos minimamente invasivostornaram-se as principais vias de tratamento e reduziram drasticamente a indicação de ureterolitotomia convencional. O último guideline publicado em 1997, baseado em metanálise da literatura, sugere a litotripsia extracorpórea como a primeira opção de tratamento para a maioria dos cálculos ureterais. Após aelaboração dessas diretrizes, surgiram séries demonstrando excelentes resultados com a utilização de aparelhos endourológicos mais finos, fontes de energia a laser e ureterolitotomialaparoscópica. Essas publicações suportam e credenciam essas técnicas como opções de tratamento para cálculos ureterais e provavelmente serão cogitadas em um próximo guideline mais atualizado. Particularmente em relação à litíase ureteral proximal, os resultados da litotripsia extracorpórea e das técnicasendourológicas são inferiores em comparação aos outros segmentos do ureter, principalmente se esses cálculos apresentarem dimensões acima de 10 mm. As novas abordagens e publicações demonstraram resultados superiores aos publicados no guideline de 1997, o que pode alterar as diretrizes para tratamento dos cálculos ureterais proximais. Esta revisão visa avaliar os resultados das alternativas atuais para abordagem da litíase ureteral proximal e sugerir algoritmo de tratamento.
