Acute graft thrombosis in patients who underwent renal transplant and received anticoagulant or antiplatelet agents. A systematic review and meta-analysis.

OBJECTIVES: Thrombosis is a major cause of early allograft loss in renal transplantation. Herein, we assessed the frequency of acute graft thrombosis in patients who underwent renal transplant and received anticoagulant or antiplatelet agents. METHODS: We performed a systematic review of all available case series studies of anticoagulant and/or antiplatelet prophylaxis of thrombosis in renal transplantation. The data were pooled in a proportional meta-analysis. RESULTS: Twenty-one case series were identified from 7,160 retrieved titles. A total of 3,246 patients were analyzed (1,718 treated with antiplatelet and/or anticoagulant agents and 1,528 non-treated control subjects). Allograft thrombosis occurred in 7.24% (95% CI 3.45 to 12.27%) of the patients receiving no intervention compared with 3.38% (95% CI 1.45 to 6.1%), 1.2% (95% CI 0.6 to 2.1%) and 0.47% (95% CI 0.001 to 1.79%) of the patients in the anticoagulant, aspirin, and aspirin + anticoagulant groups, respectively. The bleeding complication rate for anticoagulants was significantly higher than in the other groups. CONCLUSIONS: Our data suggests that anticoagulants, and aspirin, either alone or in association with an anticoagulant, seem to have a low frequency of acute allograft thrombosis after kidney transplantation. Higher hemorrhagic complication rates might occur when anticoagulants are used.

Fasting and 24-h urine pH in patients with urolithiasis using potassium citrate.

PURPOSE: To evaluate the correlation between the pH readings in 24-h urine and the random fasting specimen in patients with urolithiasis using 2 methods. METHODS: A total of 114 patients with urinary lithiasis using potassium citrate were prospectively analyzed. All patients collected 24-h urine and an additional sample, after nocturnal fasting, collected on the day they brought the 24-h sample at the lab. Two different methods (test strip and digital meter) were used to determine pH values. RESULTS: The pH analysis using strips in the 24-h urine presented a mean value similar to the one obtained in the fasting sample (6.07 ± 0.74 vs. 6.02 ± 0.82, respectively; P > 0.05). The same behavior was seen considering the readings with a digital pH meter (5.8 ± 0.78 vs. 5.75 ± 0.83; P > 0.05). However, readings conducted in the same specimen with pH meter and test strip were dissonant (P < 0.05), suggesting that the colorimetric method is not reliable in the assessment of urinary pH in this population. CONCLUSION: pH assessment in a random urinary specimen proved as efficient as the 24-h urine standard method to monitor patients with kidney stones in the use of potassium citrate. Classical test strip analysis is not sensitive enough to evaluate the urine pH in this population and digital pH meter reading is preferred.

Impact of Time-Zero Biopsy on the Outcome of Transplanted Kidneys.

BACKGROUND: A low supply of donated organs led to the expansion of criteria for kidney transplantation (KT), and the impact on late glomerular function rates (eGFR) is still uncertain. This study aimed to correlate the histologic findings at time-zero biopsy (TzB) with the final eGFR, to identify criteria that could help achieve a more thorough preimplantation evaluation of the organ. METHODS: Records from 395 adult deceased KTs were reviewed. TzBs were analyzed considering histologic criteria by compartment (vascular, interstitial, tubular, and inflammatory) and correlated with the eGFR after 1 year. RESULTS: Among donors, 56.9% were men (mean age 39 years), with the main causes of death being brain trauma (44.2%) and stroke (46.0%). Histologic analysis of TzB revealed 6.0% of glomerulosclerosis; 18.8% presenting vascular alterations; interstitial fibrosis in 54.6%; tubular changes in 76.9%, and nonspecific inflammatory infiltrate in 2.3%. Linear regression analysis showed that the main histologic findings that had impact in the eGFR were interstitial fibrosis (P = .000), followed by tubular alterations (P = .036) and glomerulosclerosis (P = .008). CONCLUSIONS: Histologic variables like interstitial fibrosis and tubular alterations show the most significant negative correlation with final eGFR. The effect of glomerulosclerosis may not be as important as formerly suggested in the literature.

Pelvic floor muscle strength is correlated with sexual function.

PURPOSE: Sexual performance is related to proprioception and pelvic floor muscle strength (PFMS). The aim of this study was to correlate sexual activity and orgasm with PFMS. MATERIALS AND METHODS: A total of 140 healthy continent female were prospectively distributed into 4 groups according to age: Group 1 (G1), 30-40; Group 2 (G2), 41-50; Group 3 (G3), 51-60; Group 4 (G4), over 60 years old. Evaluated parameters were: frequency of sexual activity and orgasm achievement; body mass index (BMI) and objective evaluation of PFMS using perineometer and surface electromyography. RESULTS: BMI was higher in G4 compared to G1 (p=0.042). Women who reported sexual activity was significantly higher in G1 compared to G3 and G4 (94.1% vs. 66.7% and 37.5%, respectively; p=0.001). Orgasm was more frequently in G1 compared to G3 and G4 (91.2% vs. 63.9% and 28.1%, respectively; p=0.001), demonstrating that sexual activity and orgasm decrease after age 51. The duration of PFM contraction was significantly higher in women who had sexual intercourse (p=0.033) and orgasm (p=0.018). CONCLUSIONS: Although the frequency of sexual intercourse and orgasm may decrease with aging, a relationship between sexual activity and PFMS remains apparent, once both sexually active women and those who have orgasms showed better PFM endurance than non-sexually active ones.

Effects of tadalafil to prevent injury on corpus cavernosum after vascular or nervous peri-prostatic bundle injury. Experimental model in rats.

PURPOSE: To evaluate the effects of tadalafil (TD) in preventing histological alterations of the corpus cavernosum caused by isolated lesions of cavernous nerve (ILCN) and artery (ILCA) in rats. METHODS: Fifty male Wistar rats were randomly assigned in five groups: G1: control; G2: bilateral ILCN; G3: bilateral ILCA; G4: ILCN+TD; G5: ILCA+TD. The cavernous bodies were submitted to histomorphometry, immunohistochemistry and biochemical analysis. RESULTS: Nerve density was significantly higher in G2 and G4 compared to control (22.62±2.84 and 19.53±3.47 vs. 15.72±1.82; respectively, p<0.05). Smooth muscle density was significantly lower in G2 and G3 in comparison to G1 (12.87±1.90 and 18.93±1.51 vs. 21.78±1.81, respectively; p<0.05). A significant decrease in the sinusoidal lumen area was observed in G2 compared to controls (5.01±1.62 vs. 9.88±3.66, respectively; p<0.05) and the blood vessel density was increased in G2 and G3 (29.32±4.13 e 20.80±2.47 vs. 10.13±2.71, p<0.05). Collagen density was higher in G3 compared to G1 (93.76±15.81 vs. 64.59±19.25; p<0.05). CONCLUSIONS: Histomorphometric alterations caused by ILCN were more intense than those produced by vascular injury, but the collagen analyses showed more fibrosis in animals with ILCA. TD was effective in preventing the majority of the alterations induced by the periprostatic bundle injury.

Impact of adjusted kidney volume measured in the bench surgery on one-year renal function in kidney transplantation.

BACKGROUND: Kidney transplantation is the treatment of choice in patient with end stage chronic kidney disease, offering the best long term survival and greater Quality of Life in this group of patients. Graft volume was correlated with improved renal function in living donor transplantations. The primary aim of this study was to correlate renal volume adjusted to body surface area with renal function one year (estimated glomerular filtration rate; eGFR) after kidney transplantation. METHODS: This single-center, prospective cohort study included 256 patients who underwent kidney transplantation from January 2011 through December 2015 at Hospital das Clínicas de Botucatu-UNESP. We evaluated three kidney measurements during the bench surgery; the final graft volume was calculated using the ellipsoid formula and adjusted to body surface area. RESULTS: In the living donors there was positive correlation between adjusted graft volume and eGFR (r = 0.311, p = 0.008). Multivariate analysis revealed that low rejection rate and increased adjusted graft volume were independent factors correlated with eGFR. In deceased donors, there was no correlation between adjusted kidney volume and eGFR (r = 0.08, p = 0.279) in univariate analysis, but a multivariate analysis indicated that lower kidney donor profile index (KDPI), absence of rejection and high adjusted kidney volume were independent factors for better eGFR. CONCLUSION: Adjusted kidney volume was positively correlated with a satisfactory eGFR at one year after living donor and deceased donor transplantations.

Pelvic floor muscle training and electrical stimulation as rehabilitation after radical prostatectomy: a randomized controlled trial.

[Purpose] To investigate the effect of electrical stimulation and pelvic floor muscle training on muscle strength, urinary incontinence and erectile function in men with prostate cancer treated by radical prostatectomy. [Subjects and Methods] One hundred twenty-three males were randomized into 3 groups 1 month after RP: (G1, n=40) control; (G2, n=41) guideline: patients were instructed to perform three types of home exercises to strengthen the pelvic floor and (G3, n=42) electrical stimulation: patients in this group were also instructed to perform exercises as group G2, and also received anal electro-stimulation therapy, twice a week for 7 weeks. The primary outcome assessment was based on the measurement of the recovery of pelvic floor muscle strength between groups. Secondary outcomes were: 1 hour Pad Test, ICIQ-SF, IIEF-5 and IPSS. Data were obtained preoperatively and at 1, 3 and 6 months after surgery. [Results] There was no significant difference in the demographic data among groups. Greater urinary leakage and pelvic floor muscle weakness in the first month compared to pre treatment improved after 3 and 6 months postoperative, without difference among groups. [Conclusion] The muscle strength recovery occurs independently of the therapy employed. Pelvic floor exercises or electrical stimulation also did not have an impact on the recovery of urinary continence and erectile function in our study.

A case report of venous thrombosis after kidney transplantation - We can save the graft? Time is the success factor.

INTRODUCTION: Venous thrombosis is a serious surgical complication that frequently results in loss of kidney graft. CASE PRESENTATION: We report the case of a female patient recipient of a decease kidney transplant that in the tenth postoperative presented with hematuria, graft pain and oliguria. Ultrasound examination was suggestive of venous thrombosis with abnormal doppler waveform pattern and reversal of diastolic flow. She underwent emergency surgical intervention after 2h of diagnosis. The vein thrombus was removed by perfusing the renal graft artery with 1000ml of Euro-Collins solution. The patient evolves with recovery of renal function after 1 week of the procedure DISCUSSION: Similar reports of graft rescue in the vein thrombosis are scarce and that the time of diagnosis to intervention is a determining factor. CONCLUSION: Rapid diagnosis of exactly 2h combined with the early re-operation may be successful in preserving renal graft in cases of venous thrombosis.

Single-port retroperitoneal renal biopsy using standard urological instruments.

OBJECTIVE: To describe the surgical technique and initial experience with a single-port retroperitoneal renal biopsy (SPRRB). MATERIALS AND METHODS: Between January and April 2013, five children underwent SPRRB in our hospital. A single 1.5 cm incision was performed under the 12th rib at mid-axillary line, and an 11 mm trocar was inserted. A nephroscope was used to identify the kidney and dissect the perirenal fat. After lower pole exposure, a laparoscopic biopsy forceps was introduced through the nephroscope working channel to collect a renal tissue sample. RESULTS: SPRRB was successfully performed in five children. The mean operative time was 32 minutes, and mean estimated blood loss was less than 10 mL. The hospital stay of all patients was two days because they were discharged in the second postoperative day, after remaining at strict bed rest for 24 hours after the procedure. The average number of glomeruli present in the specimen was 31. CONCLUSION: SPRRB is a simple, safe and reliable alternative to open and videolaparoscopic approaches to surgical renal biopsy.

What is the ideal core number for ultrasound-guided prostate biopsy?

PURPOSE: We evaluated the utility of 10-, 12-, and 16-core prostate biopsies for detecting prostate cancer (PCa) and correlated the results with prostate-specific antigen (PSA) levels, prostate volumes, Gleason scores, and detection rates of high-grade prostatic intraepithelial neoplasia (HGPIN) and atypical small acinar proliferation (ASAP). MATERIALS AND METHODS: A prospective controlled study was conducted in 354 consecutive patients with various indications for prostate biopsy. Sixteen-core biopsy specimens were obtained from 351 patients. The first 10-core biopsy specimens were obtained bilaterally from the base, middle third, apex, medial, and latero-lateral regions. Afterward, six additional punctures were performed bilaterally in the areas more lateral to the base, middle third, and apex regions, yielding a total of 16-core biopsy specimens. The detection rate of carcinoma in the initial 10-core specimens was compared with that in the 12- and 16-core specimens. RESULTS: No significant differences in the cancer detection rate were found between the three biopsy protocols. PCa was found in 102 patients (29.06%) using the 10-core protocol, in 99 patients (28.21%) using the 12-core protocol, and in 107 patients (30.48%) using the 16-core protocol (p=0.798). The 10-, 12-, and 16-core protocols were compared with stratified PSA levels, stratified prostate volumes, Gleason scores, and detection rates of HGPIN and ASAP; no significant differences were found. CONCLUSIONS: Cancer positivity with the 10-core protocol was not significantly different from that with the 12- and 16-core protocols, which indicates that the 10-core protocol is acceptable for performing a first biopsy.

Comparative study between porcine small intestinal submucosa and buccal mucosa in a partial urethra substitution in rabbits.

PURPOSE: Several urethral conditions may require tissue substitution. One collagen-base biomaterial that recently emerged as an option is small intestinal submucosa (SIS). The aim of this study was to compare the results of SIS and buccal mucosa for urethral substitution in rabbits. MATERIALS AND METHODS: Thirty-six North Folk male rabbits were randomized into three groups. In all animals, a 10 × 5 mm urethral segment was excised, and the urethral defect was repaired using a one-layer SIS patch (group I [GI]); four-layer SIS (group II [GII]); or buccal mucosa (group III [GIII]). Urethrography was performed preoperatively and after 12 weeks. After sacrifice, graft retraction was objectively measured using Scion Image(®) computer analysis and by calculation of ellipse area. The grade of fibrosis, inflammatory reaction, vascular/epithelial regeneration, and collagen III/I ratio were analyzed by hematoxylin/eosin and Picrosirius red staining. RESULTS: Urethrography confirmed a wide urethral caliber without any signs of strictures after surgery. Urethral fistulae was diagnosed in 8.3% of cases (1 animal each group). Average graft shrinkage was 55.2% in GI; 44.2% in GII; and 57.2% in GIII (p<0.05). The intensity of chronic inflammation, fibrosis, epithelium regeneration, and neovascularization was similar in all groups (p>0.05). Collagen III/I ratio was higher in GII (GI: 119.6; GII: 257.2 and GIII: 115.0); p<0.01. CONCLUSIONS: The four-layer SIS is more advantageous than the one-layer SIS and buccal mucosa for urethral substitution in rabbits.

Cold renal ischemia: comparison of efficacy between two techniques of cooling, in a swine model.

OBJECTIVES: In a swine model of renal ischemia, we compared the effectiveness of the transurethral retrograde cold saline perfusion technique to the traditional method of renal cooling with ice slush, in achieving adequate parenchymal temperatures for functional preservation of the organ. Physiological and histological effects were also assessed. METHODS: Twenty-four domestic male pigs were sampled into four groups to be submitted to a 60-minute ischemia of the left kidney without cooling, with either one of the two cooling techniques (cold saline retrograde perfusion or ice slush), or sham surgery. All of them had also a concomitant right nephrectomy. Renal cortical and medullary temperatures were recorded throughout the experiment. Urinary output was measured, and serum renal function tests were carried on, pre- and postoperatively. After 5 days, the animals were euthanized and their kidneys were submitted to histological analysis. RESULTS: Mean renal temperature fell in both groups submitted to kidney cooling. With ice slush, a faster drop was observed and a lower minimum temperature was achieved (5.0 degrees C in the cortex and 6.3 degrees C in the medulla, vs. 25.4 degrees C and 24.9 degrees C with retrograde cooling). In the other groups, temperature was unchanged. Urinary output and serum creatinine worsened after the experiment, but without significant differences among groups. The histological analysis showed no differences among the four groups, for the studied ischemia time. CONCLUSIONS: Ice slush and retrograde perfusion of cold saline are both effective for cooling the kidney during ischemia. Ice slush is faster in doing so, and it allows much lower temperatures to be achieved in the renal parenchyma. With ischemia time of 60 minutes, no significant differences on the occurrence of functional and histological alterations were detected, even for the group without a cooling procedure.

Laparoscopic aortoiliac surgery for treatment of limb critical ischemia: report of the first case in Brazil

A cirurgia videolaparoscópica vem evoluindo como alternativa cirúrgica menos invasiva para o tratamento da doença aterosclerótica oclusiva aorto-ilíaca. O objetivo deste relato é demonstrar os resultados da primeira cirurgia videolaparoscópica realizada no Brasil para o tratamento da doença oclusiva aorto-ilíaca, associada a procedimentos híbridos distais para lesões ateroscleróticas multissegmentares em paciente com isquemia crítica. A técnica videolaparoscópica é mais uma ferramenta minimamente invasiva, viável, segura e eficaz para o tratamento da doença oclusiva aorto-ilíaca extensa. A referida técnica, que nada mais é do que a cirurgia convencional realizada sob visão laparoscópica, tem bons resultados a longo prazo, associados à elegância técnica.

Laparoscopic surgery has been increasingly used as a less invasive surgical option for the treatment of aortoiliac occlusive atherosclerotic disease. The objective of this case report is to describe the results of the first laparoscopic surgery conducted in Brazil for the treatment of the aortoiliac occlusive disease associated with distal hybrid procedures to treat multisegmental atherosclerotic lesions in a patient with critical limb ischemia. The laparoscopic technique is an additional minimally invasive tool, being feasible, safe, and effective for the treatment of extensive aortoiliac occlusive disease. This technique, which is nothing more than a conventional surgery performed under laparoscopic viewing, brings good long-term results associated with technical elegance.

Prevalência e implicações da incontinência urinária e fecal em mulheres / Prevalence and implications of urinary and fecal incontinence in women

Avaliar a prevalência da incontinência urinária (IU) e fecal em mulheres atendidas no ambulatório geral do Centro de Saúde Escola - Botucatu - SP. Foram escolhidas 807 mulheres aleatoriamente responderam um questionário aplicado por entrevistadores previamente selecionados e treinados, após assinarem termo de consentimento livre e esclarecido aprovado pelo CEP. Foram distribuídas em dois grupos: GI (n=567), mulheres sem perda de urina, e grupo G2 (n=240), com perda urinária. A média de idade no GI foi de 52 anos e no G2 de 51, não havendo diferença estatisticamente significativa entre os grupos. A prevalência de incontinência urinária foi de 29,7 porcento e em 59,2 porcento a urgência estava associada. O índice de massa corpórea (IMC) foi significativamente mais alto no grupo com perda de urina em relação às mulheres continentes. Na análise de outras variáveis não houve diferença estatisticamente significativa entre os grupos estudados. No grupo de mulheres incontinentes, observou-se número significativamente mais alto de partos vaginais nas mulheres com urgência e incontinência fecal em relação às continentes. A obesidade pode ser fator contributivo ou mesmo de piora da IU. A incontinência, seja urinária de urgência ou fecal, está relacionada a número mais alto de partos vaginais.

Our objective was to evaluate the prevalence of urinary incontinence in women seen at the general outpatient service of Health-School Unit of Botucatu - UNESP. 807 women answered a questionnaire applied by interviewers previously selected and trained, after signing a free informed consent approved by CEP. They were divided into 2 groups: GI (n=567) with women without urine loss and group G2 (n=240) with urine loss. Mean age in group GI was 52 years and 51 years in G2. There was no statistically significant diference between both groups. Urinary incontinence prevalence was 29.7 percent, and in 59.2 percent of cases urgency was associated. Body mass index (BMI) was significantly higher in the group with urine loss when compared to the continent women. By analyzing other variables there was no statistically significant difference between both groups. In the incontinent group, there was a significantly higher number of vaginal deliveries in women with urgency. Considering fecal loss, vaginal deliveries had a significantly higher number among incontinent than continent women. Obesity can either contribute of worsen urinary incontinence. Fecal or urge incontinence is related to the higher number of vaginal deliveries.

Urodinâmica convencional versus cistometria simplificada para caracterização da incontinência urinária feminina / Conventional urodynamics versus simplified cystometry for characterization of female urinary incontinence

Objetivo: avaliar a concordância dos diferentes parâmetros urodinâmicos comparados à cistometria simplificada, permitindo uma diminuição na relação custo-benefício no diagnóstico da incontinência urinária de esforço (IUE) na mulher. Métodos: foram coletadas e avaliadas retrospectivamente as informações contidas dos prontuários de trinta pacientes acompanhadas, no período de janeiro de 2000 a março de 2001. Todas foram submetidas a exame físico geral e ginecológico. O estudo urodinâmico foi realizado pela técnica convencional, utilizando-se aparelho Dynograph Recorder R-611. A cistometria simplificada foi realizada com auxílio de um equipo em "Y" de PVC (pressão venosa central), conectado a um sonda de Foley 14 F, que permitia tanto a infusão de soro fisiológico como a captação da pressão intra-vesical. Foram analisados os parâmetros: volume residual, capacidade vesical, complacência, presença de contrações involuntárias do detrusor e perdas urinárias aos esforços. Para determinação da proporção de concordância entre os métodos foram utilizados o teste de concordância de Pearson e o teste de Wilcoxon, para amostras relacionadas. Resultados: a média de idade foi de 50 anos, com extremos variando de 28 a 70 anos. O índice de concordância entre os estudos, na demonstração das perdas urinárias aos esforços, foi de 67 por cento. Para a detecção das contrações involuntárias do detrusor, a proporção de concordância foi de 90 por cento. A média do volume residual encontrado na cistometria simplificada foi de 16,8 ml contra 2 ml da urodinâmica convencional, com diferença significativa (p < 0, 01). A média de capacidade vesical máxima no estudo urodinâmico foi de 440,5 ml enquanto que, na cistometria simplificada, foi de 387 ml (p < 0,05). A complacência vesical foi, em média, significativamente maior na cistometria simplificada (43,0 ml/cmH2O) quando comparada ao estudo urodinâmico (31,5 ml/cmH2O), com p < 0,01. Conclusão: avaliações preliminares sugerem que a propedêutica uroginecológica associada à cistometria simplificada é uma opção a ser considerada na avaliação clínica e pré-operatória de pacientes com IVE em substituiçâo à urodinâmica convencional, particularmente onde esta última não se encontra disponível. A cistometria simplificada é um exame acessível que é capaz de detectar contrações involuntárias do detrusor, assim como identificar perdas urinárias com relativa sensibilidade, proporcionando ao examinador noções fidedignas do comportamento vesical.
