Reconstrução total da cobertura cutânea do pênis com retalho miocutâneo: relato de caso / Total reconstruction of the skin coverage of the penis with myocutaneous flap: case report

Introdução: O pênis é uma importante estrutura do corpo masculino, sendo sua reconstrução um desafio. Existem diversas doenças e deformidades que acometem este órgão, sendo necessário, em certos casos, a reconstrução total da cobertura cutânea do pênis, tendo já sido descritas na literatura diversas técnicas, tais como o uso de enxertos totais, retalho escrotal, retalhos miocutâneos da fáscia lata e outros. Relato de Caso: Neste relato é apresentada uma reconstrução da cobertura total do pênis por meio do uso de retalho miocutâneo do músculo cremaster com pele da bolsa escrotal, conseguindo prover uma boa vascularização e mantendo a permeabilidade uretral. Conclusão: Tal técnica não foi encontrada em nenhuma das bases de dados pesquisadas no trabalho, apenas semelhantes, e mostrouse como uma boa opção para a reconstrução total da cobertura cutânea peniana.

Introduction: The penis is an important structure of the male body, and its reconstruction is a challenge. Several diseases and deformities affect this organ, being necessary, in certain cases, for the total reconstruction of the cutaneous coverage of the penis, having already been described in the literature several techniques, such as the use of total grafts, scrotal flap, myocutaneous flaps of the fasciae latae and others. Case Report: In this report, a reconstruction of the total coverage of the penis is presented using a myocutaneous flap of the cremaster muscle with skin from the scrotum, achieving good vascularization and maintaining urethral permeability. Conclusion: This technique was not found in any of the databases researched in this study, only similar ones, and it proved to be a good option for the total reconstruction of penile skin coverage.

Ultrashort anisoperistaltic end-to-side ureteroureterostomy in renal transplantation / Anastomose uretero-ureteral término-lateral anisoperistáltica ultracurta no transplante renal

ABSTRACT The improvement of surgical techniques in kidney transplantation aims to reduce the incidence of post-transplant complications, contributing to the reduction of hospital stay, related costs, morbidity and mortality, in addition to improving the quality of life of patients. The choice of the best technique is influenced by several factors and the most common technique for urinary tract reconstruction in transplants is performed with implantation of the ureter of the graft in the caudal position, with the anastomosis performed in the bladder. However, the kidney pole can be inverted and the graft ureter anastomosis can be performed directly on the recipient's ureter, facilitating venous and ureteral anastomoses and reducing urological complications.

RESUMO O aprimoramento das técnicas cirúrgicas no transplante renal tem o objetivo de reduzir a incidência de complicações pós-transplante, contribuindo com a redução do tempo de internamento hospitalar, os custos relacionados, a morbidade e a mortalidade, além de melhorar a qualidade de vida dos pacientes. A escolha da melhor técnica é influenciada por diversos fatores e a técnica mais comum de reconstrução do trato urinário nos transplantes é a realizada com implante do ureter do enxerto na posição caudal, com a anastomose feita na bexiga. No entanto, pode-se inverter o polo do rim, posicionando o polo inferior cranialmente e realizar a anastomose do ureter do enxerto diretamente no ureter do receptor, facilitando a anastomose ureteral e diminuindo as complicações urológicas.

Right atrium tumor extension through the inferior vena cava. considerations about nine cases operated under cardiopulmonary bypass

Abstract Introduction: Adrenocortical and renal cell carcinomas rarely invade the right atrium (RA). These neoplasms need surgical treatment, are very aggressive and have poor prognostic and surgical outcomes. Case series: We present a retrospective cohort of nine cases of RA invasion through the inferior vena cava (four adrenocortical carcinomas and five renal cell carcinomas). Over 13 years (2002-2014), nine patients were operated in collaboration with the team of urologists. Surgery was possible in all patients with different degrees of technical difficulty. All patients were operated considering the imaging examinations with the aid of CPB. In all reported cases (renal or suprarenal), the decision to use CPB with deep hypothermic circulatory arrest (DHCA) on surgical strategy was decided by the team of urological and cardiac surgeons. Conclusion: Data retrospectively collected from patients of public hospitals reaffirm: 1) Low incidence with small published series; 2) The selected cases did not represent the whole historical casuistry of the hospital, since they were selected after the adoption of electronic documentation; 3) Demographic data and references reported in the literature were presented as tables to avoid wordiness; 4) The series highlights the propensity to invade the venous system; 5) Possible surgical treatment with the aid of CPB in collaboration with the urology team; 6) CPB with DHCA is a safe and reliable option; 7) Poor prognosis with disappointing late results, even considering the adverse effects of CPB on cancer prognosis are expected but not confirmed.

Cistite glandular associada à metaplasia intestinal com extravasamento de mucina: relato de caso / Glandular cystitis associated to intestinal type metaplasia with mucin extravasation: a case report

A mucosa vesical, na presença de agentes agressores, sofre alterações inicialmente benignas, mas com a cronicidade pode sofrer modificações potencialmente metaplásicas. A cistite glandular apresenta um quadro sintomático inespecífico, sendo necessária a realização de biópsia para seu diagnóstico e diferenciação histológica, podendo dividir-se em subtipos clássico e intestinal. Após análise de prontuário médico pertencente ao Hospital Santa Rita de Maringá, objetiva-se relatar o caso de um paciente masculino, de 32 anos, com disúria e dor em hipogástrico, apresentando em ultrassonografia lesão cística de 3,8 cm de diâmetro na bexiga. Após a retirada da lesão por ressecção transuretral, a análise histopatológica revelou presença de ninhos de Von Brunn, áreas de epitélio mucossecretor e mucina extracelular na mucosa vesical, propondo a existência de lesão glandular com metaplasia intestinal. Foi realizado estudo imunohistoquímico para diagnóstico diferencial de adenocarcinoma mucossecretor bem diferenciado. A cistite glandular, quando manifestada macroscopicamente, assemelha-se a uma neoplasia por apresentar um aspecto irregular, difuso e algumas vezes ulceroso. Seu diagnóstico e tratamento podem ser simultâneos, porém, nos casos mais graves, as opções terapêuticas são restritas. O diagnóstico diferencial é extremamente importante para afastar a possibilidade de adenocarcinoma vesical, portanto, é imprescindível o acompanhamento periódico dos pacientes após o tratamento com a realização de exames específicos. O uso de marcadores imunohistoquímicos tem se tornado relevante para o correto diagnóstico, pois genes relacionados ao ciclo celular, como o fator de transcrição homebox 2 do tipo caudal (CDX2), podem representar um vínculo entre o surgimento de metaplasia e sua possível progressão a adenocarcinoma.

The bladder's mucosa, in the presence of aggressive agents, undergoes initially benign changes, but with chronicity may undergo potentially metaplastic modifications. Glandular cystitis presents nonspecific symptoms and biopsy is necessary for diagnosis and histological differentiation, subdividing it into classic and intestinal subtypes. After analyzing a medical record belonging to the Santa Rita Hospital from Maringá, the objective of this study is to report the case of a 32-year-old male patient with dysuria and pain in the hypogastric region, presenting on ultrasonography cystic lesion of 3.8 cm of diameter in the bladder. After removal of the lesion by transurethral resection, the histopathological analysis revealed the presence of Von Brunn nests, areas of mucosecretory epithelium and extracellular mucin in the bladder's mucosa, suggesting the existence of a glandular lesion with intestinal metaplasia. It was performed an immunohistochemical study for differential diagnosis of well-differentiated mucosecretory adenocarcinoma. Glandular cystitis, when manifest-ed macroscopically, resembles a neoplasm, since it can present an irregular aspect, diffuse and sometimes ulcerous. The diagnosis and treatment can be simultaneous, but in severe cases, the therapeutic options are restricted. Differential diagnosis is extremely important to rule out the possibility of bladder adenocarcinoma, therefore it is essential to follow up patients after treatment with specific tests periodically. The use of immunohistochemical markers has become rele-vant for the correct diagnosis, since genes related to the cell cycle, such as caudal type homeobox transcription factor 2 (CDX2), may represent a link between the onset of metaplasia and its possible progression to adenocarcinoma (AU)

Transient Distal Penile Corporoglanular Shunt as an Adjunct to Aspiration and Irrigation Procedures in the Treatment of Early Ischemic Priapism

PURPOSE: Ischemic priapism, a compartment syndrome, requires urgent treatment in order to nourish the corpora cavernosa. As the first step, aspiration of blood and irrigation of the cavernosal bodies is performed to prevent fibrotic activity and secure erectile capability. During aspiration, there are risks of cardiovascular side effects of adrenergic agonists. We aimed to evaluate a transient distal penile corporoglanular shunt technique in place of aspiration and irrigation techniques for treatment of early ischemic priapism. MATERIALS AND METHODS: A transient distal penile shunt was applied to 15 patients with early ischemic priapism between January 2011 and May 2012. Priapism duration, history, causes, pain, and any prior management of priapism were assessed in all patients. A complete blood count and penile Doppler ultrasonography were performed, which showed attenuated blood flow in the cavernosal artery. A sterile closed system blood collection set, which has two needles and tubing, was used for the transient distal penile shunt. RESULTS: Ten of 15 patients with early ischemic priapism were successfully treated with this transient shunt technique. No additional procedures were needed after the resolution of rigidity in the 10 successfully treated patients. CONCLUSIONS: The transient nature of this technique is an advantage over aspiration and irrigation in the treatment of early ischemic priapism. Our results indicate that the technique can be offered for patients with an ischemic priapism episode of no more than 7 hours.

The beginning of the 21st century: a paradigm shift in the surgical management of renal cell carcinoma in South America

PURPOSE: The incidence of renal cell carcinoma (RCC) has been rising by 2.3 to 4.3 percent every year over the past three decades. Previously, RCC has been known as the internist’s tumor; however, it is now being called the radiologist’s tumor because 2/3 are now detected incidentally on abdominal imaging. We compared patients who were treated toward the end of the 20th century to those treated during the beginning of the 21st century with regard to RCC size and type of surgical treatment. MATERIALS AND METHODS: The study included 226 patients. For analysis of tumor size, we considered a cut point of < 4 cm and > 4 cm. For analysis of type of surgery performed, we considered radical and partial nephrectomy. RESULTS: After the turn of the century, there was a reduction of 1.57 ± 0.48 cm in the size of the RCC that was operated on. Nephron sparing surgeries were performed in 17 percent of the cases until the year 2000, and 39 percent of the tumors were < 4 cm. From 2001, 64 percent of the tumors measured < 4 cm and 42 percent of the surgeries were performed using nephron sparing techniques. Mean tumor size was 5.95 cm (± 3.58) for the cases diagnosed before year 2000, and cases treated after the beginning of 21st century had a mean tumor size of 4.38 cm (± 3.27). CONCLUSIONS: Compared with the end of the 20th century, at the beginning of the 21st century due to a reduction in tumor size it was possible to increase the number of nephron sparing surgeries.

Obesidade como fator de risco para a falha da cirurgia de Burch / Obesity as a risk factor to Burch surgery failure

Objetivo: observar o impacto da obesidade e de outros fatores de risco sobre a taxa de falha das pacientes submetidas à cirurgia de Burch para tratamento da incontinência urinária. Métodos: estudo de casos de pacientes submetidas à cirurgia de Burch no período de 1992 a 2003. As pacientes foram avaliadas no momento da segunda consulta pós-operatória (66 dias em média) e com um ano de acompanhamento, e classificadas em dois grupos: Continentes e Não Continentes. As variáveis analisadas foram: idade, paridade, índice de massa corpórea (IMC), tempo de menopausa, tempo de terapia de reposição hormonal, avaliação urodinâmica, história de infecção do trato urinário, cirurgia prévia para incontinência urinária, diabetes, cistocele e prolapso uterino, tempo de internação, necessidade de autossondagem, micção espontânea no pós-operatório e ferida operatória. Os dados foram analisados com o pacote estatístico Statistical Package for Social Sciences 14.0. Foram utilizados o teste t de Student ou Mann-Whitney, para comparação das variáveis contínuas, e os testes exato de Fisher e χ2, para variáveis categóricas (p<0,05). Resultados: no momento da segunda avaliação pós-operatória, não houve diferença significativa entre os dois grupos quanto às variáveis analisadas. Com um ano de seguimento, de um total de 97 pacientes, 81 apresentavam-se continentes e 16, não continentes, sendo o IMC e a altura diferentes entre os grupos. No Grupo Continente, o IMC médio foi 27,1 e a altura de 1,57 m e, no Não Continente, 30,8 (p=0,02) e 1,52 m (p=0,01). A Odds Ratio para IMC>30 foi 3,7 (IC95%=1,2-11,5). ConclusÕES: a obesidade mostrou-se um importante fator de risco para a falha da cirurgia no primeiro ano de acompanhamento. Os resultados demonstram que pacientes com IMC>30 têm chance 3,7 vezes maior de apresentarem-se não continentes após um ano da cirurgia de Burch em relação às não obesas.

Purpose: to observe the impact of obesity and other risk factors on the rate of failure in patients submitted to Burch’s surgery for the treatment of urinary incontinence. Methods: cases study of patients submitted to Burch’s surgery, from 1992 to 2003. Patients were evaluated at the second post- surgery appointment (average 66 days) and after one-year follow-up, and classified in two groups: Continent and Non-continent. Variables analyzed were: age, parity, body mass index (BMI), menopause duration, duration of hormonal therapy, urodynamic evaluation, history of urinary tract infection, previous urinary incontinence surgery, diabetes, cystocele and uterine prolapse, time spent in hospital, necessity of self-probing, post-surgical spontaneous micturition, and surgical wound. Data were analyzed with the Statistical Package for Social Sciences 14.0 statistical package. For the comparison of continuous variables, Student’s t-test or Mann-Whitney test were used, and Fisher exact and χ2 tests, for the categorical variables (p<0.05). Results: at the second post-surgical evaluation, there was no significant difference between the two groups, concerning the variables analyzed. After one-year follow-up, from a total of 97 patients, 81 were continent and 16, non-continent, BMI and height being different between the groups. In the continent group, average BMI was 27.1 and height, 1.57 m, and, among the non-continent, 30.8 (p=0.02) and 1.52 m (p=0.01). The BMI>30 Odds Ratio was 3.7 (CI95%=1.2-11.5). ConclusionS: obesity has shown to be an important risk factor for the surgery failure in the first follow-up year. Results show that patients with BMI>30 have 3.7 times more chance of being non-continent one-year after Burch’s surgery than non-obese patients.

The York-Mason technique for recto-urethral fistulas

OBJECTIVE: Recto-urethral fistula formation following radical prostatectomy is an uncommon but potentially devastating event. There is no consensus in the literature regarding the treatment of these fistulas. We present here our experiences treating recto-urethral fistulas. MATERIAL AND METHODS: We analyzed 8 cases of rectourethral fistula treated at our institution in the last seven years. Seven of the patients underwent repair of the fistula using the modified York-Mason procedure. RESULTS: The causes of the fistula were radical retropubic prostatectomy in five patients, perineal debridement of Fournier's gangrene in one, transvesical prostatectomy in one and transurethral resection of the prostate in the other patient. The most common clinical manifestation was fecaluria, present in 87.5 percent of the cases. The mean time elapsed between diagnosis and correction of the fistula was 29.6 (7-63) months. One spontaneous closure occurred after five months of delayed catheterization. Urinary and retrograde urethrocystography indicated the site of the fistula in 71.4 percent of the cases. No patient presented recurrence of the fistula after its correction with the modified York-Mason procedure. CONCLUSION: The performance of routine colostomy and cystostomy is unnecessary. The technique described by York-Mason permits easy access, reduces surgical and hospitalization times and presents low complication and morbidity rates when surgically correcting recto-urethral fistulas.

OBJETIVO: As fístulas reto-uretrais são de acesso difícil e por vezes complexo, sendo seu fechamento espontâneo raro. Com o diagnóstico precoce e aumento do número de intervenções, principalmente a cirurgia por adenocarcinoma da próstata localizado, sua incidência apesar de rara vem crescendo. Nós demonstramos a nossa experiência dos casos de fístulas reto-uretrais entre 2000 a 2006 com uma serie de oito pacientes, sendo que sete realizaram correção da fístula pela Técnica de York Mason modificada. MATERIAL E MÉTODO: Nos retrospectivamente analisamos os prontuários de todos os casos de fístulas reto-uretrais tratados no nosso serviço no período de 2000 a 2006. Sete de oito pacientes realizaram reparo da fístula através do procedimento de York Mason modificado. RESULTADOS: Cinco pacientes tiveram a fístula como conseqüência da Prostatectomia Radical Retropúbica, sendo os outros três após debridamento devido a Fasceíte de Fournier, Prostatectomia Transvesical e Ressecção Transuretral da Próstata. A fecalúria foi o quadro clínico prevalente em 87,5 por cento dos casos, o tempo médio entre o diagnóstico e a correção da fístula foi de 29,6 (7-63 meses) ocorreu um fechamento espontâneo após cinco meses de sondagem vesical de demora, a Uretrocistografia Retrograda e Miccional demonstrou a localização da fístula em 71,4 por cento. Nenhum paciente apresentou recidiva da fístula após correção pela técnica de York Mason modificada. A colostomia foi realizada em 50 por cento dos casos e não ocorreram casos de incontinência fecal ou estenose anal. CONCLUÇÃO: Após identificação de fístula reto-uretral, não é necessário à realização de colostomia e cistostomia de rotina. Sua correção pela técnica descrita por York Mason modificada nos propicia fácil acesso a sua localização, diminui o tempo cirúrgico e de internação, com baixos índices de complicações e morbidade.
