BACKGROUND:
Various prediction tools have been developed to predict biochemical recurrence (BCR) after radical prostatectomy (RP); however, few of the previous prediction tools used serum prostate-specific antigen (PSA) nadir after RP and maximum tumor diameter (MTD) at the same time. In this study, a nomogram incorporating MTD and PSA nadir was developed to predict BCR-free survival (BCRFS).
METHODS:
A total of 337 patients who underwent RP between January 2010 and March 2017 were retrospectively enrolled in this study. The maximum diameter of the index lesion was measured on magnetic resonance imaging (MRI). Cox regression analysis was performed to evaluate independent predictors of BCR. A nomogram was subsequently developed for the prediction of BCRFS at 3 and 5 years after RP. Time-dependent receiver operating characteristic (ROC) curve and decision curve analyses were performed to identify the advantage of the new nomogram in comparison with the cancer of the prostate risk assessment post-surgical (CAPRA-S) score.
RESULTS:
A novel nomogram was developed to predict BCR by including PSA nadir, MTD, Gleason score, surgical margin (SM), and seminal vesicle invasion (SVI), considering these variables were significantly associated with BCR in both univariate and multivariate analyses (P < 0.05). In addition, a basic model including Gleason score, SM, and SVI was developed and used as a control to assess the incremental predictive power of the new model. The concordance index of our model was slightly higher than CAPRA-S model (0.76 vs. 0.70, P = 0.02) and it was significantly higher than that of the basic model (0.76 vs. 0.66, P = 0.001). Time-dependent ROC curve and decision curve analyses also demonstrated the advantages of the new nomogram.
CONCLUSIONS
PSA nadir after RP and MTD based on MRI before surgery are independent predictors of BCR. By incorporating PSA nadir and MTD into the conventional predictive model, our newly developed nomogram significantly improved the accuracy in predicting BCRFS after RP.

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.

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.

ObjectiveTo explore the practicability and safety of the F4.8 visual miniature nephroscope in the diagnosis and treatment of hematospermia.
METHODSThis study included 12 cases of refractory hematospermia accompanied by perineal or lower abdominal pain and discomfort. All the patients failed to respond to two months of systemic anti-inflammatory medication and local physiotherapy. Seminal vesicle tumor and tuberculosis were excluded preoperatively by rectal seminal vesicle ultrasonography, MRI or CT. Under epidural anesthesia, microscopic examination was performed with the F4.8 miniature nephroscope through the urethra and ejaculatory duct orifice into the seminal vesicle cavity, the blood clots washed out with normal saline, the seminal vesicle stones extracted by holmium laser lithotripsy and with the reticular basket, the seminal vesicle polyps removed by holmium laser ablation and vaporization, and the seminal vesicle cavity rinsed with diluted iodophor after operation.
RESULTSOf the 10 patients subjected to bilateral seminal vesiculoscopy, 3 with unilateral and 2 with bilateral seminal vesicle stones were treated by holmium laser lithotripsy, saline flushing and reticular-basket removal, 2 with seminal vesicle polyps by holmium laser ablation and vaporization, and the other 3 with blood clots in the seminal vesicle cavity by saline flushing for complete clearance. The 2 patients subjected to unilateral seminal vesiculoscopy both received flushing of the seminal vesicle cavity for clearance of the blood clots. The operations lasted 10-55 (25 ± 6) minutes. There were no such intra- or post-operative complications as rectal injury, peripheral organ injury, and external urethral sphincter injury. The urethral catheter was removed at 24 hours, anti-infection medication withdrawn at 72 hours, and regular sex achieved at 2 weeks postoperatively. The patients were followed up for 6-20 (7 ± 2.3) months, during which hematospermia and related symptoms disappeared in 10 cases at 3 months and recurrence was observed in the other 2 at 4 months after surgery but improved after antibiotic medication.
CONCLUSIONSThe F4.8 visual miniature nephroscope can be applied to the examination of the seminal vesicle cavity and treatment of seminal vesicle stones and polyps, with the advantages of minimal invasiveness, safety and reliability.

In the past two decades, with the rapid development of assisted reproductive technology and particularly the technological advances in male infertility microsurgery, many obstructive azoospermia-related infertile couples can now acquire the chances of natural pregnancy via reconstruction of the seminal tract. This article highlights the latest advances in surgical reconstruction of the seminal tract for the treatment of obstructive azoospermia, such as the application of laparoscopic and robotic techniques, with a discussion on microsurgical epididymal sperm aspiration and preservation, potential use of absorbable sutures or the bio-suture tape for microsurgical anastomosis in the management of obstructive azoospermia.

Objective:
To investigate the success rate and safety of percutaneous vasoseminal vesiculography with the disposable vasographic interventional therapy kit (VITK).
METHODS:
This study included ninety-six 19-65 (mean 43) years old male patients with infertility, hematospermia, seminal vesicle cyst, ejaculatory duct cyst, ejaculatory dysfunction, or vas deferens injury, with disease courses varying from 1 month to 7 years. With an open, multi-centered, single-group, self-controlled design and using the disposable VITK, we treated the patients by percutaneous vasoseminal vesiculography via injection of contrast medium into the vas deferens cavity under local anesthesia.
RESULTS:
Percutaneous vasoseminal vesiculography was successfully performed in 92 (97.87%) of the patients, which revealed abnormal seminal ducts in 51 cases (54.3%). Among the 28 infertile patients, 3 were found with bilateral and 5 with unilateral vas deferens obstruction. Vesiculitis was detected in 36 (81.8%) of the 44 hematospermia patients and bilateral vas deferens abnormality in 5 (38.5%) of the 13 patients with ejaculatory dysfunction. Transectional damage was observed in 2 patients with vas deferens injury induced by bilateral inguinal hernia repair. Three cases of seminal vesicle cyst and 4 cases of ejaculatory cyst were definitely diagnosed by vasoseminal vesiculography.
CONCLUSIONS
The disposable vasographic interventional therapy kit, with the advantages of simple operation and high safety, deserves a wide clinical application in vasoseminal vesiculography.

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.

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.

National Journal of Andrology 2017;23(11):1038-1042
Seminal vesiculoscopy is a new technology in uro-andrology developed in recent 10 years, which is a set of clinical operational techniques for observing the ejaculatory duct, seminal vesicle, ampullar region of the vas deferens and their surrounding structure, determining the cause, location and degree of the disease, and accomplishing such treatment procedures as irrigation, resection, incision, fulguration, hemostasis, expansion, drainage, and removal of hematocele, stones or obstruction in the distal seminal duct region. Therefore, it is not only an etiologically diagnostic technique, but also a minimally invasive surgical approach to the management of common diseases of the distal seminal duct region. Seminal vesiculoscopy has irreplaceable advantages of safety, effectiveness, minimal invasiveness, rapid recovery, and few complications.
