Application of transurethral seminal vesiculoscopy in uroandrology / 中华男科学杂志

With the continuous improvement of living conditions, increasing attention is being drawn to the genitourinary health of males, which has boomed the development of uroandrology in recent years. Refractory hemospermia, infertility, and perineal pain are commonly seen in some male patients, and mainly relied on medical imaging for diagnosis in the past, which, however, has a high pseudopositive rate and cannot give an etiological explanation. Patients with these diseases often adopt conservative treatments such as medication and physiotherapy, often with poor prognosis, and those suffering frequent recurrence used to be treated by transurethral resection, laparoscopic surgery or open surgery, which are now rarely employed due to their high rate of postoperative complications, slow recovery, and easy recurrence. In recent years, transurethral seminal vesiculoscopy has gained a wide application in the diagnosis and treatment of the above-mentioned uroandrological diseases and shown its advantages of high clinical effectiveness and low incidence of complications. The review updates on the indications, methods, skills and clinical application of transurethral seminal vesiculoscopy.

Ectopic seminal tract opening in enlarged prostatic utricle: A report of 22 cases / 中华男科学杂志

Objective@#To explore the diagnosis, classification and treatment of ectopic seminal tract opening in enlarged prostatic utricle (EPU).@*METHODS@#We retrospectively analyzed the clinical data on 22 cases of ectopic seminal tract opening in EPU confirmed by spermography, EPU open cannula angiography or intraoperative puncture of the vas deferens and treated by transurethral incision of EPU, cold-knife incision or electric incision of EPU, full drainage of the anteriorwal, and open or laparoscopic surgery from October 1985 to October 2017.@*RESULTS@#Five of the patients were diagnosed with ectopic opening of the vas deferens and the other 17 with ectopic opening of the ejaculatory duct in EPU. During the 3－48 months of postoperative follow-up, symptoms disappeared in all the cases, semen quality was improved in those with infertility, and 2 of the infertile patients achieved pregnancy via ICSI.@*CONCLUSIONS@#Ectopic seminal tract opening in EPU is rare clinically. Spermography is a reliable method for the diagnosis of the disease, and its treatment should be aimed at restoring the smooth flow of semen based on proper classification and typing of the disease.

Clinical outcomes of transperitoneal laparoscopic unroofing and fenestration under seminal vesiculoscopy for seminal vesicle cysts / 亚洲男科学杂志(英文版)

Symptomatic seminal vesicle cysts (SVCs), especially those of a large size, can be removed by surgical treatments. Currently, open surgeries for SVC are rarely performed due to their extensive surgical trauma, and minimally invasive surgical therapies for treating seminal vesicle cysts are still in the early stages. In addition, relevant studies are mostly confined to case reports. In this study, we retrospectively reviewed 53 patients who had received transperitoneal laparoscopic unroofing or fenestration under seminal vesiculoscopy for SVC in our institution. Both surgeries decreased the cyst volume to a significant extent; however, according to the remnant lesion size after rechecking images, seminal vesiculoscopic fenestration tended to have a higher recurrence than laparoscopic unroofing. Regarding complications, two individuals in the laparoscopic unroofing group experienced ureteral injury and rectal injury, while patients in the fenestration group only had temporary hemospermia, which indicates that fenestration surgery tends to have less severe complications than laparoscopic unroofing. There was no solid evidence confirming semen improvement after these surgical therapies in our study. Future studies with a prospective design, larger sample size, and longer follow-up period are required to verify and further explore our findings.

Transurethral seminal vesiculoscopy for recurrent hemospermia: experience from 419 cases / 亚洲男科学杂志(英文版)

We summarized our experience in transurethral seminal vesiculoscopy (TSV) for recurrent hemospermia by introducing surgical techniques, intraoperative findings, and treatment outcomes. TSV was performed in 419 patients with an initial diagnosis of persistent hemospermia at Shanghai Changhai Hospital (Shanghai, China) from May 2007 to November 2015. TSV was successfully performed in 381 cases (90.9%). Hemospermia was alleviated or disappeared in 324 (85.0%) patients by 3 months after surgery. Common intraoperative manifestations were bleeding, obstruction or stenosis, mucosal lesions, and calculus. Endoscopic presentation of the ejaculatory duct orifice and the verumontanum was categorized into four types, including 8 (1.9%), 32 (7.6%), 341 (81.4%), and 38 (9.1%) cases in Types A, B, C, and D, respectively. TSV is an effective and safe procedure in the management of seminal tract disorders. This study may help other surgeons to become familiar with and improve this procedure. However, further multicentric clinical trials are warranted to validate these findings.

Two Different Surgical Approaches for Prostatic Stromal Sarcoma: Robot-Assisted Laparoscopic Radical Prostatectomy and Open Radical Cysto-Prostatectomy With Ileal Conduit

Stromal sarcoma of the prostate is very rare and shows rapid growth, which consequently is related to poor prognosis. Recently, we treated two cases of prostatic stromal sarcoma: one with robot-assisted laparoscopic radical prostatectomy and the other with open radical cysto-prostatectomy with an ileal conduit. To the best of our knowledge, this is the first case report of a prostatic stromal sarcoma managed by use of a robotic procedure. Here, we report of our experiences in the treatment of prostatic stromal sarcoma by use of two different methods.

¿Es siempre necesaria la resección de las vesículas seminales durante la prostatectomía radical? / Is seminal vesicle resection always needed during radical prostatectomy?

Introducción: Estudios recientes en pacientes con cáncer de próstata (CP) en estadios precoces han propuesto preservar las VS en la prostatectomía radical (PR) por tener una baja probabilidad de infiltración tumoral, obteniendo una mejor potencia y continencia que en pacientes sometidos a PR “clásica”. El objetivo de esta comunicación fue identificar factores clínico-patológicos preoperatoriosasociados al hallazgo de VS comprometidas en la pieza quirúrgica definitiva. Secundariamente determinarla evolución en el tiempo de este estadio (T3b) y su influencia en la sobrevida libre de enfermedad. Materiales y Métodos: Se revisaron los registros de 632 pacientes con diagnóstico de CP sometidos a PR por enfermedad localizada (T1 - T2) entre 1999 al 2005 en el Hospital Universidad Católica de Chile (HUC) y 1990 al 2005 en el Hospital Sótero del Río (HST). La recidiva bioquímica y sobrevida fue certificada a través de registros clínicos, entrevista telefónica, certificados de defunción y mediciones seriadas de APE. Se definió como recidiva bioquímica a la medición de APE > 0,4 ng/ml. Las variables analizadas en la regresión fueron: la edad y porcentaje de cáncer en la biopsia transrectal como variables continuas y Ape preop (< 10, 10-20,> 20) y puntaje de gleason en la biopsia transrectal (< 7, 7, > 7) como variables categorizadas. Se determinó la sensibilidad (Sen), especificidad (Esp),curvas ROC y área bajo la curva (AUC) para definir el mejor valor de corte que se asociara a compromiso de VS. Resultados: Del total de la serie, 74 pacientes (11,7 percent) presentaron compromiso de VS. El análisis de regresión logística reveló que el porcentaje de cáncer y puntaje de Gleason en la biopsia transrectal fueron factores predictores independientes de compromiso de VS...

Introduction: Recent studies in patients with prostate cancer (PC) in early stages proposed seminalvesicles sparing in radical prostatectomy (RP) due to a low probability of infiltration and better continenceand potency results. The purpose of this communication was to identify preoperative clinical and pathological data associated with seminal vesicles prostate cancer involvement. Secondarily, weassessed the evolution of patients with stage (T3b) disease treated with seminal vesicle sparing(SVS) technique and its influence on disease-free survival. Materials and Methods: Retrospective analysis of data of 632 patients with PC who underwent RP for localized disease (T1 - T2) from 1999 to 2005 at HUC and from 1990 to 2005 at HST. Biochemical recurrence and survival were verified through clinical records, telephone calls and serial PSA measurements. Biochemical recurrence was defined as PSA >0.4 ng / ml. Variables in the regression analysis were: Age and percentage of cancer disease identified in cores from transrectal prostate biopsy were defined as continuous variables. Preop psa (<10 10-20,>20) and Gleason score on biopsy transrectal (<7, 7,> 7) were defined as categorical variables. sensitivity (Sen), specificity (Esp) and ROC curves were calculated to define the best cutting value to be associated with SVS. Results: Seventy four patients (11.7 percent) had received SVS. Logistic regression analysis revealed that the percentage of cancer and Gleason score on transrectal biopsy were independent predictive factors predicting successful surgery treatment with SVS. The best cutoff point using the percentage of cancer in transrectal biopsy was 14.4 percent, with a Sen of 54 percent...

Congenital seminal vesicle cyst in a 3 years old boy [A case report]

Cysts of the seminal vesicle, although rare, are well recognized clinical entities which are now seen with increasing frequency with modern pelvic imaging modalities. These cysts may be unilateral or bilateral; congenital or acquired. Seminal vesicle cysts may arise from inflammation of the seminal vesicle or from embryological remnants such as Mullarian duct. Surgical removal has been the treatment of choice either by an abdominal or laparoscopic approach. Here we present a case of seminal vesicle cyst of congenital type in a 3 year old boy, who also had a non-functioning left pelvic ectopic kidney

Cálculo de vesícula seminal tratado por cirurgia videolaparoscópica: relato do primeiro caso brasileiro / Seminal vesicle stone treated by laparoscopic surgery: report ofthe first Brazilian case

A ocorrência de cálculo de vesícula seminal é uma entidade rara, compoucos relatos na literatura mundial, sendo ainda mais escassos artigossobre o tratamento videolaparoscópico. A importância do diagnósticoestá relacionada ao fato de o cálculo de vesícula seminal ser um fatorna gênese da prostatite e ter relação com dor perineal e na ejaculação,simulando quadro de prostatite sem infecção demonstrável. Relatamoso caso de um paciente de 36 anos com quadro de dor perineal epolaciúria persistente, apesar de tratamento clínico adequado. Atomografia e a ecografia transretal diagnosticaram cálculo de istmode vesícula seminal bilateral. A vesiculectomia seminal bilateral porlaparoscopia resultou em remissão da sintomatologia e controle dainfecção em seguimento de seis anos.

Small round blue cell tumor of seminal vesicle in a young patient

Seminal vesicle tumor is a rare disease with unclear origin. Generally, it is presented as a pelvic mass that can be detected by sonography and digital rectal exam. The authors report a 25-year-old patient with a pelvic mass which the magnetic resonance and surgical specimen reveal a seminal vesicle tumor. Immunohistochemical findings favored a primitive neuroectodermal tumor of the seminal vesicle. Herein, the treatment, histological and histochemical findings of this entity are discussed.

Ultrasonido transrectal como guía para el diagnóstico y tratamiento de la obstrucción de los conductos eyaculadores / Transrectal us for diagnosis and treatment of ejaculatory duct obstruction

Introducción: La infertilidad masculina es causada en el 10 por ciento de los casos por obstrucción de las vías seminales (ViS). Cuando la obstrucción ocurre a nivel de los conductos eyaculadores (OCE) la resección transuretral (RTU) del verumontanum resulta una terapéutica efectiva. El objetivo de este trabajo es demostrar la utilidad del ultrasonido transrectal (USTr) intraoperatorio y la inyección transrectal contrastada de las ViS bajo radioscopia (RX) para determinar la causa y localización de la OCE y facilitar la RTU guiando al resectocopio en forma precisa hacia el sitio de obstrucción. Material y métodos: Entre junio 2001 y abril 2004 se evaluaron 7 pacientes con sospecha de OCE. Todos presentaban examen físico normal, espermograma con hipospermia (5= oligospermia y 2= azoospemia) y dilatación de las vesículas seminales (ViS). La técnica consistió en la punción de la porción dilatada de las ViS y la inyección de contraste iodado y azul de metileno bajo USTr, RX y uretroscopia. Una vez determinado el sitio de obstrucción se realizó la RTU, cuyo trayecto y magnitud fueron determinados por el USTr. El éxito terapéutico fue determinado en base a la mejoría del espermograma. Resultados. En todos (7/7) se arribó a un diagnóstico, encontrándose quistes de la línea media (n=4) estenosis del conducto eyaculador (ECE) bilateral (n=1), unilateral (n=1) e hipotonía de VS (n=1). Excepto este último (obstrucción funcional) todos fueron sometidos a RTU sin complicaciones. En todos los pacientes tratados (6/7) los espermogramas mejoran a los valores deseados. Conclusión: El USTr es un método útil para determinar la causa y el sitio de obstrucción de las ViS. Permite guiar la punción diagnóstica y facilita la labor de la RTU determinando en forma precisa y tiempo real el sitio y trayecto a resecar. De esta forma se realizan cirugías dirigidas con menor área de resección y menor número de potenciales complicaciones
