Histological Comparison of Buccal and Lingual Mucosa Grafts for Urethroplasty: Do They Share Tissue Structures and Vascular Supply?

Comparable outcomes were published using a buccal mucosa graft (BMG) from the cheek and a lingual mucosa graft (LMG) from the sublingual area, for urethral augmentation or substitution. To date, no histological comparison between both grafts has been conducted. We histologically assessed BMG and LMG harvested during urethral surgeries, aiming to compare graft properties and vascular support. We conducted a prospective single cohort study, including oral mucosa urethroplasty patients. During surgery, graft dimensions and donor sites were collected, and a 0.5 × 0.5 cm sample was obtained from the prepared graft. Formalin-fixed paraffin-embedded samples were sliced at 4 micrometres (µm) and hematoxylin-eosin stained. Using a telepathology tool, all slides were digitalized and measured from 10× to 40× magnification. In each graft, global and individual layers thicknesses were assessed, including vascular density and area. Descriptive and comparative (parametrical and non-parametrical) statistical analysis occurred. We collected 57 grafts during 33 urethroplasties, with 30 BMG and 22 LMG, finally, included. The mean age was 56.6 (SD 15.2) years, and the mean graft length was 5.8 (SD 1.7) cm and the width was 1.7 (SD 0.4) cm. The median graft thickness was 1598.9 (IQR 1200-2100) µm, the mean epithelium layer was 510.2 (SD 223.7) µm, the median submucosa was 654 (IQR 378-943) µm. the median muscular was 477.6 (IQR 286-772) µm, the median vascular area was 5% (IQR 5-10), and the median adipose tissue area was 5% (IQR 0-20). LMG were significantly longer and narrower than BMG. Total graft thickness was similar between LMG and BMG, but the epithelium and submucosa layers were significantly thinner in LMG. The muscular layer was significantly thicker in LMG. Vascular density and vascular areas were not significantly different between both types of grafts. LMG showed significantly less adipose tissue compared with BMG. Our findings show LMG and BMG for urethroplasty surgeries share the same thickness and blood supply, despite having significantly different graft sizes as well as mucosal and submucosal layers thickness.

Sexual function after anterior urethroplasty: a systematic review.

BACKGROUND: Urethral surgery outcomes are often evaluated by assessing urinary flow and urethral patency. However, sexual consequences may appear after urethroplasty, impairing quality of life and patient's perception of success.The aim of this study is to assess the relationship between anterior urethral reconstruction and postoperative sexual dysfunction, including the proposed factors predicting sexual outcomes. METHODS: We searched in PubMed database using the terms: "anterior urethroplasty", bulbar urethroplasty" or "penile urethroplasty", and "sexual dysfunction", "erectile function" or "ejaculation". Articles were independently evaluated for inclusion based on predetermined criteria. Systematic data extraction was followed by a comprehensive summary of evidence. RESULTS: Thirty-eight studies were included for final analysis. No randomised trial on the topic was found. Urethral surgery might affect different aspects of sexual function: erectile function, ejaculatory function, penile shape and length, and genital sensitivity, leading to severe sexual dysfunction. Patient perception of sexual impairment was related to post-operative satisfaction. CONCLUSIONS: Sexual dysfunction after anterior urethral reconstruction is an important issue that must be appropriately discussed during preoperative patient counselling. Reported outcomes after anterior urethroplasty should include sexual consequences and relevance, evaluated using validated tools.

Long-Term Undesirable Consequences of Penile Skin Island Flap to Correct Penoescrotal Transposition: A Case Report and Review of Literature.

Hypospadias is a congenital malformation of the male lower urinary tract, consisting of a ventral urethral opening proximal to the glans penis. This condition is corrected surgically in the paediatric age, with a great variety of techniques available. Traditionally, a tubularized genital skin was used for one- or two-stage repairs. Nowadays, the tendency is to use preputial or oral mucosa grafts, dorsally located, to avoid diverticula formation and prevent hair growth in the neourethra. We present a case of a patient born with proximal hypospadias with penoscrotal transposition, surgically corrected in his childhood, using dorsal penile skin island flap. The patient is referred to urology consultation in his adulthood for a weak urinary stream, recurrent infections, and a large amount of hair exiting through the urethral meatus.

Evaluación del impacto sobre la actividad sexual de un programa de rehabilitación pulmonar para pacientes con enfermedad pulmonar obstructiva crónica / Assessment of the impact of pulmonary rehabilitation on sexual activity in patients with chronic obstructive pulmonary disease

ANTECEDENTES Y OBJETIVO: La enfermedad pulmonar obstructiva crónica (EPOC) limita la calidad de vida, teniendo consecuencias sobre la esfera sexual. Los programas de rehabilitación respiratoria (PRR) ayudan al tratamiento de estos pacientes. Analizamos la actividad sexual de pacientes con EPOC y los resultados de un PRR. PACIENTES Y MÉTODOS: Estudio prospectivo de cohorte única en varones diagnosticados de EPOC y candidatos a PRR. Evaluación clínica, respiratoria y analítica (T, LH, FSH, estradiol y progesterona). International Index of Erectile Function (IIEF) al inicio y tras 6 meses de PRR. Análisis descriptivo inicial, comparando parámetros respiratorios según actividad sexual. Análisis de cambios tras el PRR mediante IIEF y satisfacción mediante el cuestionario Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS). RESULTADOS: Entre 2014 y 2016, 62 varones incluidos. Edad media: 66,5 años (SD 7,2); 52 exfumadores. Diez eran sexualmente activos (16,1%). No detectamos alteraciones hormonales. No apreciamos diferencias significativas en parámetros respiratorios (FEV1, test de marcha de 6 min, número de exacerbaciones, puntuación en CAT) entre pacientes sexualmente activos y no activos. Puntuación media inicial IIEF: función eréctil 8, función orgásmica 4, deseo sexual 5,6, satisfacción con relaciones 5,3 y satisfacción global 4,5. Tras PRR, aumento significativo en la puntuación total del IIEF: 6,1 (IC95% 1,9-10,3). Mejoría en todos los dominios, con cambio significativo en satisfacción con relaciones: 0,9 (IC95% 0,2-1,6). Moderada satisfacción con el tratamiento según EDITS. CONCLUSIONES: Solo un pequeño porcentaje de pacientes con EPOC incluidos en un PRR son activos sexualmente. No se aprecian diferencias respiratorias entre los pacientes activos y no activos. Los PRR provocan mejoría global en la función sexual, particularmente en la satisfacción con las relaciones

BACKGROUND AND OBJECTIVE: Chronic obstructive pulmonary disease (COPD) affects life quality, and also sexual activity. Pulmonary rehabilitation (PR) is a helpful treatment in COPD patients. The aim of this study is to assess sexual activity on COPD patients, and the effect of PR over it. PATIENTS AND METHODS: Single cohort prospective study over male COPD candidates to PR. Clinical, respiratory and biochemical assessment (FSH, LH, T, and progesterone) was performed. Patients were asked to fill baseline International Index of Erectile Function (IIEF) questionnaire, and 6 months after PR. A descriptive initial analysis compared respiratory values between patients with and without sexual activity. Changes in IIEF results were assessed after PR, and satisfaction with treatment using Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS). RESULTS: Between 2014 and 2016, 62 male COPD patients enlisted. Mean age: 66.5 years (SD 7.2). 52 Ex-smokers. 10 declared being sexually active (16.1%). No hormonal levels alterations. No significant differences on respiratory parameters between sexually active and non-active patients (FEV1, 6-minutes walking test, number of exacerbations, CAT score). Baseline mean IIEF values: Erectile function 8, orgasmic function 4, sexual desire 5.6, intercourse satisfaction 5.3, and overall satisfaction 4.5. After PR, significant increase in mean IIEF value: 6.1 (CI95% 1.9-10.3). Improvement was found in all domains, with statistical significance on intercourse satisfaction 0.9 (CI95% 0.2-1.6). Moderate satisfaction with treatment was achieved according to EDITS. CONCLUSIONS: Only a low percentage of COPD males included in PR is sexually active. No pulmonary differences were found between sexually active and non-active patients. PR improves sexual function, particularly intercourse satisfaction domain

Bladder endometriosis and endocervicosis: presentation of 2 cases with endoscopic management and review of literature.

Urinary tract endometriosis and endocervicosis are an uncommon pathologic finding, with a common embryological origin. We present 2 cases of female patients with bladder mass. The first one was a finding of a nodular formation in the bladder during study of a nonviable foetus and the second was an incidental finding of a neoformation in the fundus of the bladder during the realization of an ultrasound. In both cases, we performed a surgical management with transurethral resection. Histopathological examination revealed a bladder endometrioma in the first case and endocervicosis with associated endometriosis in the second.

OBJECTIVES: From August 1997 to December 2004 we performed 47 vasovasostomies for vasectomy reversal in the same number of patients. Only 42 patients are available for follow-up, with a mean follow-up of at least six months. Mean age is 40.7 years for the patients and 30.8 for the couples. METHODS: The two-layer technique was applied under microscope magnification in the first 22 patients; single layer technique was performed in the others. RESULTS: Overall spermatozoid patency rate was 71.42%, and pregnancy rate was 32.45%. Surgical technique did not have influence on results. CONCLUSIONS: Better prognosis is expected in young men; the longer the interval between vasectomy and reversal, the lower the patency rate. Regarding pregnancy rate, it is not influenced by delay of reversal

[Surgical details and complications from retransplantation into the iliac fossa for third and fourth kidney transplants]. / Aspectos quirúrgicos y complicaciones derivadas de la reutilización de la fosa ilíaca en los terceros y cuartos retrasplantes renales.

OBJECTIVES: To analyze the surgical aspects and complications from retransplantation into the iliac fossa for third and fourth kidney transplants. METHODS: Retrospective study of the 34 third and 5 fourth transplants performed in our department. We analyze patient's characteristics, surgical aspects and complications, and graft outcomes. RESULTS: Mean patient age was 41.6 years. 67% of the first and second transplants had been lost to vascular problems (19%) or chronic rejection (48%). Average time from last transplant in the retransplanted iliac fossa was 9 years (3 days-17 years). There were not significant differences between the groups of first and second transplant and third and fourth in cold ischemia time, number of mismatches, and number of days on hemodialysis after transplantation; there were significant differences in receptor age, number of transfusions, maximum and current antibodies and donor age, all of which were higher in third and fourth transplants. The graft was basically implanted in the right iliac fossa (71%) through a lumbar-iliac iterative incision; vascular anastomosis were equally made to the common and external iliac vessels; ureteral reimplant was performed following an extravesical technique; simultaneous transplant nephrectomy of the previous graft was performed in 33% of the cases. 59% of the cases had immediate diuresis and 49% did not require dialysis within the first 7 postransplant days. Surgical complications were mainly vascular: 4 cases of hemorrhage, 3 venous thrombosis and 2 arterial thrombosis. There were also 4 cases of lymphocele, 1 perirenal hematoma, and 1 enterocutaneous fistula with an abscess of the surgical bed. There were no urologic complications in the series. Globally, there was 1 death (2.5%) secondary to hemorrhage and another 6 grafts (15%) were lost to complications, 5 vascular thrombosis and 1 after surgical bed abscess. 1, 3, 5, and ten-year actuarial graft survival were 65%, 52%, 40% and 28% respectively. CONCLUSIONS: Retransplantation into the iliac fossa for third and fourth transplants is associated with a small increase in the number of surgical complications, mainly vascular complications.

[Treatment of urinary stress incontinence using suburethral implantation of tension-free vaginal tape (TVT). 4 years' experience]. / Tratamiento de la incontinencia urinaria de esfuerzo mediante el implante suburetral de cintas libres de tensión (TVT). 4 años de experiencia.

OBJECTIVES: To analyze our results in terms of continence and complications of treatment of urinary incontinence with TVT during the 4 first years. METHODS: 72 patients underwent surgery for urinary incontinence between 1999 and 2002. Chart review was performed for medical history, physical examination, urodynamic tests, surgical procedure, intraoperative and postoperative complications, objective and subjective results. RESULTS: 62 patients were diagnosed of genuine stress urinary incontinence and 10 patients of mixed urinary incontinence. 14 patients had grade 3 cystocele, 12 of them underwent associated colporrhaphy. Operations were performed under local anaesthesia in 1 patient, spinal anaesthesia in 41 and general anaesthesia in 30. Mean operation time was 32 minutes, 66 minutes when colporrhaphy was associated, and previous surgery did not increase the surgical difficulty. 6 patients (8.3%) suffered bladder perforation which was identified during cystoscopy, but only required reposition of the tape without affecting patients' outcomes; 1 patient had a pelvic hematoma that evolved without sequel; 16 patients (22.22%) had urinary retention which spontaneously resolved between 2 and 60 days, except one case that required section of the mesh. 8 patients (11.11%) developed de novo bladder instability; there were 2 cases of late mesh perforation into urethra or bladder, which were solved by endoscopic mesh section; 3 patients had voiding discomfort and 1 chronic perineum pain. 70 patients (97.3%) achieved continence under stress; nevertheless only 57 patients (79.17%) were satisfied with their outcomes. Main causes for dissatisfaction were failure, de novo instability, persistence of urgency in cases of mixed incontinence, and voiding discomfort. Previous surgery and performance of associated procedures did not influence outcomes, although they were associated with longer operation times and higher incidence of urinary retention. Patients with Valsalva's leak point pressure < 60 H2O cm had slightly worse outcomes (63.5% satisfaction). CONCLUSIONS: TVT is an easy to learn and easy to perform technique, with few complications and good results.

Tratamiento de la incontinencia urinaria de esfuerzo mediante el implante suburetralde cintas libres de tensión (TVT). 4 años de experiencia / Treatment of stress urinary incontinence by suburethral implant of tension-free vaginal tape (TVT). 4 year experience

OBJETIVO: Analizar nuestros resultados respecto de la continencia y complicaciones a lo largo de los 4 primeros años de tratamiento de la incontinencia urinaria con TVT. MÉTODO: 72 pacientes operadas entre 1999 y 2002.Se hizo una revisión de la historia clínica recogiendo los datos de anamnesis, exploración física y urodinámica, intervención quirúrgica, complicaciones intraoperatorias y evolutivas, resultados objetivos y subjetivos. RESULTADOS: 62 pacientes fueron diagnosticadas de incontinencia genuina de stress y 10 mixta. 14 pacientes tenían cistocele grado 3 practicándose colporrafia asociada en 12 de ellas. Se utilizó anestesia local en 1 paciente, raquídea en 41 y general en 30. El tiempo quirúrgico fue de 32 minutos y cuando se asoció colporrafia 66, la cirugía previa no aumentó la dificultad quirúrgica.En 6 pacientes (8,3 por ciento) hubo perforación vesical que se identificó en la cistoscopia y sólo precisó recolocación de la malla sin influir en la evolución; en 1 caso hubo hematoma pélvico sin secuelas; 16 pacientes (22,22 por ciento) tuvieron cuadros de retención que se solucionaron entre 2 y 60 días precisando en 1 de ellos la sección de la malla; inestabilidad de novo se observó en 8 casos (11,11 por ciento); perforación tardía de la malla en uretra o vejiga en 2 casos que se solucionó con la sección endoscópica de la misma; discomfort miccional en 3 casos y dolor perineal crónico en 1. La continencia al esfuerzo se logró en 70 pacientes (97,3 por ciento), sin embargo sólo 57 pacientes (79,17 por ciento) estaban satisfechas. El fracaso, la inestabilidad de novo, la persistencia de síntomas de urgencia en los casos de incontinencia mixta y el discomfort miccional fueron las principales causas de insatisfacción. La cirugía previa y la realización de procedimientos asociados no influyeron en los resultados, si bien estos últimos se asociaron a un tiempo quirúrgico mayor y a un mayor porcentaje de retención.Las pacientes con presión de fuga al Valsalva inferior a 60 cm de agua tuvieron resultados ligeramente peores (63,5 por ciento de satisfacción). CONCLUSIONES: El TVT es una técnica de fácil aprendizaje y ejecución, con escasas complicaciones y buenos resultados. (AU)

Correlación de los hallazgos por imagen y resultados anatomopatológicos en la prostatectomía radical. Datos de nuestra serie / Correlation of the imaging findings and the anatomopathological results in radical prostatectomy. Data from our series

OBJETIVOS: Analizar los métodos diagnósticos utilizados en el cáncer de próstata y el grado de información que aportan sobre la extensión tumoral preoperatoria. Comparar estos resultados, con los obtenidos a través del análisis anatomopatológico, en las piezas de Prostatectomía Radical. MÉTODOS: A través del Servicio de Admisión y Documentación Clínica, se obtuvo un listado con las Prostatectomías Radicales realizadas en el período de estudio. Se construyó una base de datos con todos los ítems objeto de estudio. Se analizaron los datos con el programa estadístico SPSS para Windows. RESULTADOS: En el período 1991-1998 se realizaron 109 Prostatectomías Radicales. Se practicó ecografía transrectal (ET) en 89 pacientes (81,6 por ciento), siendo positiva para tumor (uni o bilateral) en 77, con una sensibilidad del 86 por ciento (Intervalo de confianza del 78,8-93,2) En 94 pacientes, se realizó estudio mediante TAC, siendo positivo en 25. Sensibilidad del 26,5 por ciento (IC 17,6-35,4). La sensibilidad correspondiente a ET y TAC fue de 4,17 por ciento y de 3,33 por ciento para la afectación capsular, de 5,88 por ciento y 5,26 por ciento para la afectación de VVSS y de 0 por ciento y 0 por ciento para la afectación ganglionar, respectivamente. CONCLUSIONES: La ecografía transrectal, es un método diagnóstico fiable, aunque cuando se utiliza para comprobar la extensión tumoral presenta una baja sensibilidad. Los métodos radiológicos, presentan una baja sensibilidad cuando los utilizamos para el estudio de extensión del cáncer de próstata en nuestra serie. Puede obviarse la realización sistemática de TC preoperatoria en los cánceres de próstata (AU)

Incidencia de priapismo en el Hospital Universitario Marqués de Valdecilla de Santander / Incidence of priapism at the Marques de Valdecilla teaching hospital (Santander, Spain)

OBJETIVOS: Reflejar nuestra experiencia de priapismos, intentando comprobar su etiología, alteración en la gasometría, tratamiento y evolución. MÉTODO: Se revisan las historias del Servicio de Urología en los últimos 8 años, periodo en el que se trata a los pacientes con disfunción eréctil de forma protocolizada. RESULTADOS: Hemos recogido 9 episodios de priapismo en 8 pacientes, todos ellos de bajo flujo, en edades comprendidas entre los 37 y los 71 años. El periodo de erección no deseada varió entre las 4 y las 72 horas. De los 9 casos la etiología fue: en 7 casos PGE intracavernosa, en un caso tras toma de trazodona, y en otro caso de causa deconocida. En todos los casos se aplicó metoxamina intracavernosa, con muy buen resultado, excepto uno que precisó de shunt safeno-cavernoso y otro caso al que de entrada se aplicó adrenalina también con buen resultado. CONCLUSIONES: Desde el uso de agentes intracavernosos para el tratamiento de la disfunción eréctil (DE) el priapismo es una urgencia urológica mucho más frecuente que debemos tener presente, así como sus diversos tratamientos. Aunque con PGE está descrita una menor incidencia, debemos ajustar bien la dosis para evitar su mayor incidencia (AU)
