It is very uncommon for urothelial carcinoma to develop in an ureterocele. It is generally discovered in an imaging study or in connection with haematuria.We found very few reports in the literature. Here, we report on the case of a 71-year-old male who initially presented with haematuria and low back pain and who then underwent transurethral resection for an intraureterocele tumour. Pathology confirmed urothelial carcinoma.

ObjectivesThe objective was to submit our first experience in endoscopic inguinal lymphadenectomy (EIL), evaluate the feasibility of the procedure and carry out a review of the literature.Material and methodsA 41-year-old patient was diagnosed with penile cancer with squamous cell carcinoma pT2G1 pathology, with no palpable inguinal lymph nodes. A bilateral inguinal lymphadenectomy was performed with preservation of the saphenous vein, conventional left and endoscopic right procedures. The perioperative data is presented and that obtained is discussed in the literature.ResultsThe total time was 270 minutes, 180 for endoscopic and 90 for conventional procedures. Blood loss was minimal in both cases. Fifteen lymph nodes were dissected on the endoscopic side, and 17 in the conventional side, the latter with more pain and devitalised skin flap.ConclusionsEIL for penile cancer is feasible and there is less morbidity with an early recovery. The literature is not conclusive on the indication of EIL.

Resumo Este artigo analisa, através de processamento de sinais, a interação entre densidade de fluxo magnético e um material submetido a diferentes condições de tratamento. O objetivo é estudar o ruído gerado dessa interação e correlacionálo com o grau de fragilização do material. Um aço inoxidável duplex SAF 2205 é utilizado. Os sinais são analisados através de FFT e correlacionados com valores de energia absorvida por impacto. Os resultados mostram que as distribuições de frequências dos sinais de FFT acompanham a formação da fase que fragiliza o material e que os valores médios das amplitudes de frequências servem como parâmetro de monitoramento.Palavras-Chave Processamento de sinais, Densidade de fluxo magnético, Fragilização.Abstract This article analyzes, through signal processing, the interaction between magnetic flux density and a material submitted to different treatment conditions. The objective is to study the generated noise of this interaction and correlate it with the degree of embrittlement of the material. A duplex stainless steel SAF 2205 is used. Signals are analyzed through FFT and correlated with values of absorbed energy by impact test. The results show that the frequency distributions of the FFT signals accompany the formation of the phase that embrittle the material and that the average values of the frequency amplitudes serve as a monitoring parameter.
