Comparación de datos anatomopatológicos entre biopsia de próstata y pieza de prostatectomía radical en pacientes con cáncer de bajo y muy bajo riesgo / Comparison of pathological data between prostate biopsy and radical prostatectomy specimen in patients with low to very low risk prostate cancer

Objetivo: Analizar la correlación entre los datos anatomopatológicos encontrados en prostatectomía radical y la biopsia previa realizada en pacientes con cáncer de próstata de bajo riesgo. Material y métodos: Se ha realizado un estudio descriptivo transversal para valorar las características de las prostatectomías radicales realizadas en nuestro centro desde enero de 2012 a noviembre de 2014. Los criterios de inclusión fueron pacientes con enfermedad de bajo riesgo (cT1c-T2a, PSA ≤ 10 ng/ml y Gleason ≤ 6). Fueron excluidos aquellos con menos de 8 cilindros en la biopsia, número de cilindros afectos no especificados, tacto rectal no recogido en historia clínica o biopsia realizada en otro centro. Resultados: De las 184 prostatectomías realizadas en este periodo, 87 pacientes cumplían con los criterios de inclusión y 26 de estos presentaban < 3 cilindros afectados y un PSAd ≤ 0,15 (muy bajo riesgo). Encontramos en la muestra total un porcentaje de infragradación (Gleason ≥ 7) del 18,4% (IC 95%: 10,3-27,6%) y de afectación extracapsular (pT3) del 10,35% (IC 95%: 4,6-17,2%). El porcentaje de márgenes positivos fue del 21,8% (IC 95%: 12,6-29,9%). En el grupo de muy bajo riesgo no encontramos ningún caso de afectación extracapsular y un solo caso de infragradación (Gleason 7 [3 + 4]) representando un 3,8% del total (IC 95%: 0-12,5%). Resultaron ser variables predictoras de no correlación (estadio ≥ pT3a o infragradación) el grupo de riesgo inicial, volumen, PSA densidad y cilindros afectados. Conclusiones: El volumen prostático, el valor del PSA densidad, el número de cilindros afectados y el grupo de riesgo inicial del paciente influyen en la aparición de datos de mal pronóstico anatomopatológico en la pieza de prostatectomía radical (afectación extracapsular y Gleason ≥ 7)

Objective: To analyze the correlation between pathological data found in radical prostatectomy and previously performed biopsy in patients at low risk prostate cancer. Material and methods: A descriptive, cross-sectional study was conducted to assess the characteristics of radical prostatectomies performed in our center from January 2012 to November 2014. The inclusion criteria were patients with low-risk disease (cT1c-T2a, PSA ≤ 10 ng/mL and Gleason score ≤ 6). We excluded patients who had fewer than 8 cores in the biopsy, an unspecified number of affected cores, rectal examinations not reported in the medical history or biopsies performed in another center. Results: Of the 184 patients who underwent prostatectomy during this period, 87 met the inclusion criteria, and 26 of these had < 3 affected cores and PSA density ≤ .15 (very low risk). In the entire sample, the percentage of undergrading (Gleason score ≥ 7) and extracapsular invasion (pT3) was 18.4% (95% CI 10.3 − 27.6) and 10.35% (95% CI 4.6 − 17.2), respectively. The percentage of positive margins was 21.8% (95% CI 12.6-29.9). In the very low-risk group, we found no cases of extracapsular invasion and only 1 case of undergrading (Gleason 7 [3 + 4]), representing 3.8% of the total (95% CI 0 - 12.5). Predictors of no correlation (stage ≥ pT3a or undergrading) were the initial risk group, volume, PSA density and affected cores. Conclusions: Prostate volume, PSA density, the number of affected cores and the patient's initial risk group influence the poor pathological prognosis in the radical prostatectomy specimen (extracapsular invasion and Gleason score ≥ 7)

[Early experience in laparoscopic radical prostatectomy using the laparoscopic device for umbilical access SILS Port]. / Experiencia inicial en prostatectomía radical laparoscópica con el dispositivo de acceso laparoscópico umbilical Single-Incision Laparoscopic Surgery Port.

Since 2007, various urological procedures have been performed with laparoendoscopic single-site surgery (LESS surgery), including nephrectomy, pyeloplasty, simple prostatectomy and, with the refinement of laparoscopic instrumentation, radical prostatectomy. This paper reports our initial experience in radical prostatectomy using the SILS Port from Covidiem and two lateral 5-mm trocars for triangulation. The SILS Port allows for accurate, simple insertion through a Hadson incision. The flexible port accommodates three 5-mm cannulas or two 5-mm cannulas and a 12-mm port for easier instrument exchange through a single incision. This approach decreases morbidity from bleeding, hernia and/or internal organ damage and improves cosmetic. One-port single-incision laparoscopy is part of the natural development of minimally invasive surgery. Future research is required to assess the intraoperative and postoperative benefits of LESS surgery as compared to standard laparoscopy.

Experiencia inicial en prostatectomía radical laparoscópica con el dispositivo de acceso laparoscópico umbilical Single-Incision Laparoscopic Surgery Port® / Early experience in laparoscopic radical prostatectomy using the laparoscopic device for umbilical access SILS Port®

Desde el año 2007 se están realizando distintos procedimientos en cirugía laparoendoscópica por puerto único (laparoendoscopic single-site surgery), incluyendo nefrectomía, pieloplastia, adenomectomía prostática y, con el perfeccionamiento del instrumental laparoscópico, prostatectomía radical. Presentamos nuestra experiencia inicial en prostatectomía radical laparoscópica utilizando el dispositivo Single-Incision Laparoscopic Surgery Port® de Covidien y 2 trocares auxiliares de 5mm colocados lateralmente para triangulación. El Single-Incision Laparoscopic Surgery Port® permite una inserción precisa y sencilla a través de una incisión de Hadson. El puerto flexible contiene 3 cánulas de 5mm o 2 cánulas de 5mm y una de 12mm para facilitar el intercambio de instrumental a través de la incisión única. Este abordaje disminuye la morbilidad por sangrado, hernias y/o lesión de los órganos internos y mejora los resultados cosméticos. El puerto único forma parte del desarrollo natural de la cirugía mínimamente invasiva. Se necesita más experiencia para determinar los beneficios intra y postoperatorios de la cirugía laparoendoscópica por puerto único en comparación con la laparoscopia convencional (AU)

[Surgical complications after 160 renal transplantations. Experience. Comments]. / Complicaciones quirúrgicas tras 160 transplantes renales. Experiencia. Comentarios.

The present study reviewed the complications observed in 160 renal transplants that had been performed from 1982 to 1992. Complications were observed in 27 cases (16.87%), which falls within reasonable limits and is similar to the complication rate reported elsewhere. The treatment utilized in these cases was highly effective and only 3 grafts (1.87%) were lost. The following complications were observed: obstructive uropathy (7 cases, 4.37%), fistula (18 cases, 11.25%), vascular complications (1 case, 0.62%) and other complications (1 case, 0.62%).

[Anatomical and technical foundations of the non-hemorrhagic treatment of simple hydrocele. Technical contributions]. / Fundamentos anatómicos y técnicos del tratamiento no hemorrágico del hidrocele simple. Aportaciones técnicas.

The efficacy of the conventional surgical techniques in the treatment of simple hydrocele has been well-established. However, further insights into the embryological anatomy of the testis and its layers have led to the development of new surgical concepts. We have conducted a retrospective study after using an "avascular" technique (extravaginalization-marsupialization) with optimum results. 120 patients treated by the Wilkinson vaginal reversal were assessed for efficacy and complications. The working hypothesis and the principles based on embryological anatomy are discussed. The results and relevant data of the treated group of patients are presented.

[Gonadal stromal tumor in childhood. Report of a case. Comments]. / Tumor de estroma gonadal en la infancia. Aportación de un caso. Comentarios.

A case of testicular gonadal stromal tumor in an 8-month-old boy is described. Patient evaluation revealed no hormonal alterations. The patient underwent orchidectomy and has remained tumor-free at two years follow-up, which meets the well-established criteria for benign tumors. A detailed anatomopathological description is presented.

[The endourological treatment of distal ureteral fistulae in the kidney transplant. The exclusion or "dry" technic]. / Tratamiento endourológico de las fístulas de uréter distal en el trasplante renal. Técnica de exclusión o "seca".

The present study reports our experience in the endourological treatment of fistulas of the distal ureter in renal transplant patients. The temporary urinary exclusion or dry technique was effective in 8 of the 10 patients. We advocate the use of this simple and safe technique which achieves excellent results.
