Da Vinci vs. Hugo RAS for robot-assisted radical prostatectomy: a prospective comparative single-center study.

PURPOSE: To evaluate Hugo RAS against the Da Vinci system for Robot-Assisted Radical Prostatectomy (RARP) in prostate cancer treatment. METHODS: We compared outcomes of 150 patients with prostate cancer undergoing RARP with either Hugo or Da Vinci systems. Our analysis included operative, postoperative, pathological, and functional outcomes. RESULTS: Both groups had 75 patients. Baseline characteristics and tumor features were similar. Intraoperatively, Da Vinci had a shorter docking time (10.45 vs. 18.62 min, p = 0.02), but total operative times were comparable (145.34 vs 138.95, p = 0.85). Hugo outperformed in neck dissection and lymphadenectomy times (22 vs 13.67 min, p = 0.027 and 37.82 vs 45.77 min, p = 0.025). Postoperative metrics like stay duration, catheter time, and complications showed no significant difference. Functional results, using IPSS and IIEF5, were similar between systems. Six Da Vinci patients (8%) and nine Hugo patients (12%) experienced social incontinence (p = 0.072). Pathological outcomes like T stage, Gleason Score, and nodes removed were alike. However, Hugo had more positive surgical margins (20% vs. 10.67%, p = 0.034). CONCLUSIONS: RARP outcomes using Hugo RAS were similar to the Da Vinci system in our study. More research and extended follow-up are required to ascertain long-term oncological and functional results.

Organ-Sparing Surgery for Testicular Germ Cell Tumors: A Current Perspective.

Background and Objectives: We aimed to evaluate the oncological and functional outcomes of organ-sparing surgery for testicular germ cell tumors, a procedure that seeks to strike a balance between effective cancer control and organ preservation, in the treatment of testicular tumors. We aimed to discuss the surgical technique and complications, and determine the appropriate candidate selection for this approach. Material and Methods: A comprehensive literature search was conducted to identify relevant studies on organ-sparing surgery for testicular tumors. Various databases, including PubMed, Embase, and Cochrane Library, were used. Studies reporting on surgical techniques, complications, and oncologic and functional outcomes were included for analysis. Results: Current evidence suggests that organ-sparing surgery for testicular germ cell tumors can be considered a safe and efficacious alternative to radical orchiectomy. The procedure is associated with adequate oncological control, as indicated by low recurrence rates and low complication rates. Endocrine testicular function can be preserved in around 80-90% of patients and paternity can be achieved in approximately half of the patients. Candidate selection for this surgery is typically based on the following criteria: pre-surgery normal levels of testosterone and luteinizing hormone, synchronous or metachronous bilateral tumors, tumor in a solitary testis, and tumor size less than 50% of the testis. Conclusions: Organ-sparing surgery for testicular germ cell tumors offers a promising approach that balances oncological control and preservation of testicular function. Further research, including large-scale prospective studies and long-term follow-ups, is warranted to validate the effectiveness and durability of organ-sparing surgery and to identify optimal patient selection criteria.

[Mucinous tubular and spindle cell renal cell carcinoma: two novel cases and a literature review.] / Carcinoma mucinoso tubular y de células fusiformes renal: aportación de 2 nuevos casos y revisión de la literatura.

INTRODUCTION: Mucinous tubularand spindle cell carcinomas (MTSC) are a relativelyrare subtype of renal cell carcinoma (RCC) . Thesetumors are composed by tubular and spindle cellareas within a mucinous stroma. They are generallylow-grade nuclei tumors and limited to the kidney, sothey usually have a favorable prognosis. We report twonew cases of MTSC treated at our institution. MATERIALS AND METHODS: We reviewed therenal tumors surgery database of our hospital from2008 to 2019, selecting patients diagnosed with CMTF.We evaluated clinicopathological data and evolution ofthe patients. We also reviewed the published literatureto compare it with our findings. RESULTS: Two patients were included in the study,a 50-year-old male (case 1) and a 55-year-old female(case 2). The diagnosis was made by ultrasound asan incidental fi nding in case 1 and during the studyof fl ank pain in case 2. Treatment was surgical withpartial and radical nephrectomy respectively. After amean follow-up of 70 months, both patients are aliveand disease-free. CONCLUSION: Mucinous tubular and spindle cellcarcinomas (MTSC) is a rare renal tumor, approximatelytwo hundred cases have been published. Thereare questions yet to be answered about their diagnosisand behaviour so it is of utmost importance to reportnew cases in order to increase our knowledge and improvepatient care.

INTRODUCCIÓN: Los carcinomasmucinosos tubulares y de células fusiformes (CMTF)son un subtipo relativamente infrecuente de carcinomarenal (CCR). Están compuestos por célulastubulares y fusiformes con un estroma mucinoso.Generalmente son tumores de bajo grado y estánlimitados al riñón, por lo que habitualmente tienenbuen pronóstico. Reportamos dos nuevos casos deCMTF tratados en nuestra institución. MATERIAL Y MÉTODOS: Se realizó una revisiónde todos los tumores renales intervenidos en nuestrohospital desde el año 2008 has ta el año 2019, seleccionandolos pacientes diagnosticados de CMTF.Se evaluaron las características clinicopatológicasy la evolución de los pacientes.

[Local anesthesia significantly improves the tolerance of prostate biopsy]. / La anestesia local mejora significativamente la tolerancia de la biopsia prostática.

UNLABELLED: Transrectal biopsy is one of the most frequent procedures in urological practice. Generally, transrectal biopsies have been practiced without anesthesia, because of a supposed good tolerance. Nevertheless, it is not infrequent to find patients with a high level of pain and adverse effects attributable to such procedure. OBJECTIVES: In the present article the effect of transrectal local anesthesia in order to significantly diminish the perception of pain by the patient is evaluated. METHODS: A total of 131 consecutive patients undergoing transrectal prostate biopsy are included in the study. After randomization, 76 patients were biopsiated with anesthesia and 55 represent the control group. Cases and control groups do not differ in age or prostate volume. Anesthesia consisted on a periprostatic nerve blockage with injection of 5 cc of 1% mepivacaine solution in the angle between prostate and seminal vesicles bilaterally. A visual analogical scale for pain was used; it was given to the patient at the end of the procedure. RESULTS: Mean pain value was 2.41 with a median of 2.0 in the group with anesthesia, and 4.02 with a median of 4 in the control group. A Student's t test comparing the means showed a statistically significant difference of 1.61 (p < 0.0001). Pain in the scale was 66% greater in the control group. CONCLUSION: The use of anesthesia in the performance of transrectal biopsies significantly diminishes the perception of pain by patients. This effect, along with the tendency to increase the number of biopsies, will result in short time in a more generalized use of local anesthesia.

La anestesia local mejora significativamente la tolerancia de la biopsia prostática / Local anesthesia significantly improves the tolerance of prostate biopsy

La biopsia transrectal es uno de los procedimientos mas frecuentes en la práctica urológica. Usualmente las biopsias transrectales se han practicado sin administrarse anestesia, ante la consideración de una buena tolerancia. Sin embargo no es infrecuente encontrarnos ante pacientes con un nivel del dolor alto e incluso efectos adversos atribuibles al mismo. OBJETIVO: Se evalúa en el presente trabajo si la anestesia local transrectal puede disminuir significativamente la percepción del dolor por el paciente. MÉTODOS: Se incluyen en el siguiente estudio 131 pacientes consecutivos y sometidos a biopsia transrectal. Efectuándose la randomización 76 pacientes fueron biopsiados con anestesia y 55 representan el grupo control. Casos y controles no difieren en edad ni volumen prostático. La anestesia se efectuó administrándose 10 cc del anestésico mepivacaína al 1%, 5 cc en cada lado en el ángulo entre la próstata y las vesículas seminales. Se empleó una escala analógica y visual del dolor que se suministró al paciente una vez acabado el procedimiento. RESULTADOS: En el grupo de pacientes anestesiados la media de valoración del dolor fue de 2,41 con una mediana de 2 y en el grupo control se obtuvo una media de 4,02 con una mediana de 4. Se realizó test de comparación de medias (t de Student), obteniéndose entre los grupos una diferencia estadísticamente significativa de 1,61 (< 0,0001). Porcentualmente encontramos una diferencia en la escala del dolor de un 66 % más en el grupo control. CONCLUSIÓN: La utilización de anestesia en la realización de las biopsias transrectales disminuye significativamente la percepción del dolor por los pacientes. Este efecto junto a la tendencia en incrementar el número de biopsias, generalizará en poco tiempo el empleo de la anestesia local

[Adenocarcinoma of the female urethra: report of two cases and bibliography review]. / Adenocarcinoma de uretra femenina: presentación de dos casos y revisión de la literatura.

OBJECTIVES: Primary adenocarcinoma of the female urethra is a rare malignancy. We report two cases and a review of the latest articles focused on classification and treatment of this kind of neoplasm. METHODS: We present two females diagnosed of urethral adenocarcinoma, describing clinic and pathological features, diagnosis and treatment. CONCLUSIONS: Female urethral adenocarcinoma is an uncommon neoplasm with a heterogeneous histogenesis. The distal urethral carcinoma is more amenable to treatment, and the prognosis is better than that of proximal or entire urethral carcinoma, which is often associated with extensive local invasion and metastasis.
