RESUMEN

PURPOSE: To explore the efficacy of different approaches of seminal vesiculoscopy surgery and the predictive factors of good treatment outcome. MATERIALS AND METHODS: A retrospective analysis of 68 patients who underwent seminal vesiculoscopy for hematospermia in our hospital from January 2015 to January 2021. According to different surgical approaches, they were divided into three groups: natural ejaculatory ducts (method A, 45 cases), assisted transurethral resection/incision of ejaculatory ducts (method B, 14 cases), fenestration in prostatic utricle (method C, 9 cases). We analyzed the recurrence rate of the three surgical approaches and the predictive factors of treatment efficacy. RESULTS: The total recurrence rate after the seminal vesiculoscopy for hematospermia in this group was 32.35%. The postoperative recurrence rates of the three methods were 24.44% for method A, 50.00% for method B and 44.44% for method C, and there was no significant difference among the three methods (P > 0.05). The data of five predictors of 45 cases in method A group were included in the Univariate Logistic analysis, the results suggest that whether complicated with seminal tract stones/cysts was an effective predictor (OR 0.250, P = 0.022), which was still an effective predictor in the Multivariate Logistic analysis model (OR 0.244, P = 0.010). CONCLUSIONS: The Transurethral seminal vesiculoscopy technique demonstrates a low postoperative recurrence rate in treating hematospermia. Among the various approaches, the intraoperative use of natural orifices through the ejaculatory duct exhibits the lowest recurrence rate. Additionally, seminal tract stones/cysts effectively predict favorable postoperative outcomes.

RESUMEN

Obstructive azoospermia is a kind of common clinical disease, which often happens in epididymis, vas deferens and ejaculatory duct obstruction and accounts for male infertility. Azoospermia, which is caused by obstruction of the ejaculatory duct, is relatively rare. but the development of endoscopic technology now allows the disease to be resolved by surgery. In the past, transurethral resection of ejaculatory duct (TURED) has been used to treat patients with ejaculatory duct obstruction and azoosperm-free disease. But with the further study of TURED operation in recent years, as well as in patients with postoperative follow-up results showed that the urine - tube reflux and retrograde ejaculation ejaculation the incidence of iatrogenic injury is higherduring the TURED.therefore, in recent years, some experts committed to seeking a less damage and better effect of the surgical method. With the continuous development of endoscopic technology, seminal vesiculoscopy has come into being, which also creates conditions for further understanding the structure and function of the seminal vesicle and distal seminal duct, accurate diagnosis and minimally invasive treatment of the currently discovered diseases. In this article, we summarized the semen abnormalities associated with seminal vesiculoscopy in the treatment of ejaculatory duct obstruction, and also reviewed the surgical methods, clinical application and research progress of seminal vesiculoscopy.

RESUMEN

OBJECTIVE: To evaluate the clinical outcomes of seminal vesiculoscopy-assisted thulium laser ablation (SVS-TLA) in the treatment of oligoasthenozoospermia or azoospermia induced by ejaculatory duct obstruction (EDO). METHODS: We retrospectively analyzed the clinical data on 42 cases of EDO-induced oligoasthenozoospermia or azoospermia in our Clinic of Andrology from April 2018 to January 2020, all definitely diagnosed and treated by SVS-TLA. We followed up the patients regularly after operation, obtained their routine semen parameters at 3, 6 and 9 months postoperatively, examined them by t-test and compared them with the baseline. RESULTS: Operations were successfully completed in all the 42 cases, with an average surgery time of 52.7 minutes. Compared with the routine semen parameters collected 2 weeks before surgery, the semen volume, sperm concentration and total sperm motility of the patients were all significantly improved at 3, 6 and 9 months postoperatively (P < 0.01). Sperm were found in 40 cases at 3 months and in the other 2 cases at 6 and 9 months after surgery. Postoperative complications were observed in 7 cases, including epididymitis, perineal or testicular pain, and hematuria, which all disappeared after corresponding symptomatic treatment. No such serious complications as retrograde ejaculation, rectal injury, urethral stricture or urinary incontinence occurred in any of the cases after operation. CONCLUSION: SVS-TLA is a safe and effective option for the treatment of EDO, which can significantly improve the semen quality of the patient without causing serious postoperative complications.

RESUMEN

GEMC1 and MCIDAS are geminin family proteins that transcriptionally activate E2F4/5-target genes during multiciliogenesis, including Foxj1 and Ccno Male mice that lacked Gemc1, Mcidas or Ccno were found to be infertile, but the origin of this defect has remained unclear. Here, we show that all three genes are necessary for the generation of functional multiciliated cells in the efferent ducts that are required for spermatozoa to enter the epididymis. In mice that are mutant for Gemc1, Mcidas or Ccno, we observed a similar spectrum of phenotypes, including thinning of the seminiferous tubule epithelia, dilation of the rete testes, sperm agglutinations in the efferent ducts and lack of spermatozoa in the epididymis (azoospermia). These data suggest that defective efferent duct development is the dominant cause of male infertility in these mouse models, and this likely extends to individuals with the ciliopathy reduced generation of multiple motile cilia with mutations in MCIDAS and CCNO.

RESUMEN

BACKGROUND: Ductus deferens may manifest in a variety of anomalies such as its absence, duplication, ectopy, or diverticulum. Ectopic seminal tract opening has two main types, ectopic ejaculatory duct opening, and ectopic vas deferens opening. Generally, ductus deferens anomalies affect approximately 0.05% of the population. Patients may be asymptomatic or complaining of urinary tract infections and/or epididymitis. Most of these cases are associated with renal dysplasia. To confirm the diagnosis Cystourethroscopy catheterization and retrograde urethrogram should be performed, but the definitive diagnosis is done by vasography. The definitive treatment is complete surgical resection of the pathological urogenital connection. This case is commonly discovered while exploring other findings such as testicular torsion and inguinal hernia. CASE PRESENTATION: We report a rare case of an 11-year-old male who presented with gross hematuria and numerous congenital malformations including a left polydactyly clubfoot, polyorchidism, with several surgical procedures, and left kidney dysgenesis. Surgery was performed for a left inguinal hernia, during which a third undescended testicle was discovered incidentally and was eradicated. A retrograde urethrogram was performed to establish the diagnosis. A fistula- that is connected with the left ureter- was resected. The histopathologic findings confirmed the diagnosis of true duplication of the Vas deferens, with communication between the ureter and the vas deferens. By follow-up, the kidney function tests were within normal limits. CONCLUSIONS: This case report aims to highlight the early diagnosis and management of the duplicated vas deferens and the associated congenital malformations to improve the prognosis and kidney function and to avoid long-term complications.

RESUMEN

This study aimed to establish animal models with different degrees of ejaculatory duct obstruction. Forty-eight male rats aged 14-15 weeks were randomly divided into three groups (n = 16): control, complete ejaculatory duct obstruction (tied around the lower seminal vesicle gland and ductus deferens with a 2-0 silk ligature), and partial ejaculatory duct obstruction (padded with a wire guide). Mortality, complications, seminal vesicle morphology and histopathology were compared in the three groups at 4 and 8 weeks postoperatively. In the complete ejaculatory duct obstruction group, seminal vesicle weight decreased gradually with increased obstruction time compared with those of the control group (p < 0.05); moreover, stone-like material was occasionally observed. In the partial ejaculatory duct obstruction group, there was an increase followed by a decrease in seminal vesicle weight in the postoperative period compared with that of the control group (p < 0.05). Histopathological lesions of seminal vesicles were observed in the complete and partial ejaculatory duct obstruction groups (8 weeks postoperatively). We successfully established animal models of complete and partial ejaculatory duct obstruction, which provide an easy-to-use tool for studying seminal vesicle changes after ejaculatory duct obstruction.

RESUMEN

Genitourinary anomalies constitute a large proportion of congenital malformations. However seminal tract anomalies, particularly ejaculatory duct (ED) anomalies are very rare and little information exists on the topic. We are reporting a very rare case of bilateral ectopic EDs opening in the bladder trigone in a 33-year-old gentleman presenting for evaluation for primary infertility. The patient's semen analysis showed low-ejaculate-volume, fructose negative, acidic pH and azoospermia. His hormonal profile was normal. Cystoscopy revealed an empty posterior urethra, and the verumontanum and the openings of the EDs could not be identified in the posterior urethra. The ED openings were found inside the bladder trigone. Vasography combined with cystoscopy confirmed the opening of the ED in the trigone following Intra-vasal injection of methylene blue. Our patient had a successful intracytoplasmic sperm injection using testicular spermatozoa that resulted in a healthy baby boy. We also did a formal literature review through PUBMED, MEDLINE and Google Scholar with the search term (ectopic ED). Search results were filtered to exclude vas deferens ectopia. Our literature search revealed five studies comprising 24 patients with ectopic EDs. Mean age at diagnosis was 29.88 ± 12.88 years. The most common presenting symptom was hemospermia. The ectopic EDs most commonly opened in a midline cyst (21 cases), bladder trigone (1 case), or bladder neck (1 case). The most common management used for symptomatic patients with ectopic EDs opening in the midline cyst was through transurethral fenestration. In conclusion, ectopic ED openings in the bladder trigone are very rare. Management varies by case depending on the presentation, anatomy of underlying anomaly, associated complication/s and desire for fertility.

RESUMEN

OBJECTIVE: To explore the diagnosis and treatment of ectopic seminal duct opening into the urethra. METHODS: We reviewed the literature and retrospectively analyzed the clinical data on a case of sex development abnormality. The patient was a 16-year-old gender female seeking medical improvement of female signs, admitted to hospital with "clitoris hypertrophy, no menstruation and chromosome karyotype 46XY", treated by bilateral orchiectomy, and simultaneously examined by seminal vesiculography and cystoscopy. RESULTS: Seminal vesiculography showed the ectopic opening of the right ejaculatory duct into the urethra accompanied by dysplasia of the seminal vesicle. Cystoscopy exhibited a fissrure-like opening in the right wall of the urethra but no verumontanum. Postoperative pathology revealed bilateral undeveloped testes and epididymides. CONCLUSION: Ectopic opening of the seminal duct into the urethra is extremely rare and often complicated by many malformations, for the diagnosis of which the most reliable options are seminal vesiculography and retrograde radiography through the ectopic orifice under the cystoscope. The treatment of the disease should follow the principles of timeliness, individualization and consideration of associated malformations.

RESUMEN

OBJECTIVE: To investigate the clinical effect and safety of transutricular seminal vesiculoscopy in the treatment of refractory hemospermia. METHODS: Using 6Fr ureteroscopy through the prostatic utricle, we treated 103 cases of refractory hemospermia with distal seminal duct obstructive lesions, including 12 cases complicated by distal seminal duct cyst. We rinsed the seminal duct cavity, cleaned out the stones, removed the cyst wall with holmium laser and followed up the patients for 12 months postoperatively. RESULTS: The operations were successfully completed in all the cases but 1 (0.9%), in which the ureteroscope failed to enter the bilateral seminal vesicles. The operation time was (47 ± 9) min. No rectal injury or acute epididymitis occurred intraoperatively, nor fever, long-term dysuria or long-term hematuria after surgery. Postoperative follow-up showed that bloody semen symptoms vanished in 93 (90.3%) of the cases, improved significantly in 4 (3.9%) and not significantly in 2 (1.9%), and 3 cases of recurrence (2.9%) were all relieved after reoperation. CONCLUSION: Transutricular seminal vesiculoscopy has the advantages of clear anatomic vision, minor invasiveness and significant effectiveness in the treatment of refractory hemospermia. What's more, holmium laser is better than plasmakinetic resection in removal of the cyst wall.

RESUMEN

PURPOSE OF REVIEW: The aim of this review is to provide an overview of surgical treatment options for male infertility including varicocelectomy, treatment of ejaculatory duct obstruction, vasovasostomy, and sperm extraction, and to review recent advances in techniques and technologies that may improve operative outcomes. RECENT FINDINGS: Microscopic subinguinal varicocelectomy has been shown to have the highest success rates with lowest rates of complications, and may be facilitated by the use of Doppler, indocyanine green angiography, and the 4K3D operating video microscope. The standard treatment for ejaculatory duct obstruction by transurethral resection of the ejaculatory ducts has changed little over time, but vesiculoscopy may allow for temporary dilation of an obstruction to allow for natural conception, while also offering diagnostic capabilities. Use of the robotic platform has gained popularity for vasectomy reversals but controversy remains regarding the cost-effectiveness of this option. Recently, a reinforcing suture technique has been described for vasovasostomy to minimize anastomotic breakdown and reversal failure. Finally, gray-scale and color-enhanced ultrasound may improve ability to predict successful sperm retrieval during extraction procedures. SUMMARY: Though the fundamentals of surgical treatment options for male infertility have changed little with time, technological advancements have contributed to improved surgical outcomes over recent years.

RESUMEN

OBJECTIVE: To evaluate the effect of real-time transrectal ultrasound-guided seminal vesiculoscopy (TRUS-SVS) in the treatment of azoospermia secondary to ejaculatory duct obstruction. METHODS: This retrospective study included 40 cases of azoospermia secondary to bilateral ejaculatory ducts obstruction treated by TRUS-SVS from June 2016 to June 2018 after failure to enter the vesiculoscope through the ejaculatory duct or prostatic utricle. We analyzed the success rate of surgery, operation time, postoperative complications, treatment results, and application value of TRUS-SVS. RESULTS: Real-time TRUS-SVS was successfully performed in 36 (90.0%) of the cases, 33 through bilateral and the other 3 through unilateral seminal vesicle, with a mean operation time of (32.8 ± 16.6) min. Thirty-seven of the cases were followed up for 6-15 (mean 9.3) months, of which sperm were found in 31 at 1-3 months and in 25 at 3-12 months, and pregnancies achieved in 9 cases within 12 months after surgery. No serious complications as retrograde ejaculation, urinary incontinence and rectal injury were observed postoperatively, except 2 cases of epididymitis and 2 cases of hematuria, which were all cured. CONCLUSIONS: For the patients who failed in seminal vesiculoscopy through the ejaculatory duct or prostatic utricle, real-time TRUS-SVS is a recommended procedure with the advantages of a high success rate, less damage to the prostate and rectum, and benefit to the improvement of semen quality.

RESUMEN

OBJECTIVE: To report our experience in the diagnosis, minimally invasive treatment, and composition of seminal vesicle calculi (SVC). PATIENTS AND METHODS: In the present study, we evaluated 20 patients who were admitted to our hospital from January 2013 to January 2018. All the patients were diagnosed with intractable haematospermia and SVC. The diagnosis was further confirmed by seminal vesiculoscopy. SVC were removed by basket extraction; with larger SVC fragmented by holmium laser before extraction. Scanning electron microscopy, X-ray diffraction, and infrared spectroscopy were used to determine the SVC composition. RESULTS: All operations were completed successfully without surgical complications. SVC were mostly composed of hydroxyapatite and protein, suggesting that they were produced by infections. CONCLUSIONS: Seminal vesiculoscopy is a simple, minimally invasive technique that can be used for diagnostic confirmation and treatment of seminal vesiculitis with SVC. This study improves our understanding of SVC and provides a theoretical basis for the prevention of postoperative recurrence of SVC.

RESUMEN

BACKGROUND: Persistent or recurrent haemospermia often occurs in individuals with ejaculatory duct obstruction (EDO). This study aimed to evaluate the efficacy and safety of transurethral resection of the ejaculatory duct (TURED) combined with seminal vesiculoscopy in treating persistent or recurrent haemospermia in men with EDO. METHODS: From June 2014 to March 2018, 103 consecutive patients with EDO who underwent TURED combined with seminal vesiculoscopy for persistent or recurrent haemospermia at the Department of Urology of West China Hospital were enrolled into this retrospective study. The patients were evaluated mainly by detailed history-taking and performing semen analysis, transrectal ultrasonography, and magnetic resonance imaging. RESULTS: Among the 103 patients, 79 (76.70%) had cysts of the lower male genitourinary tract; 63 (61.17%) had blood clots; and 32 (31.07%) had calculi in the seminal vesicle and/or prostatic utricle. The duration of postoperative follow-up was 12 months, and the symptoms of haemospermia disappeared in 96 (93.20%) patients. There was no significant difference in the semen PH and sperm count before and after surgery; however, the ejaculate volume and sperm motility significantly improved postoperatively. Except for two cases of acute urinary retention and one case of watery ejaculate after surgery, no severe postoperative complications, including epididymitis, urethral stricture, urinary incontinence, retrograde ejaculation, or rectal injury, were observed. CONCLUSION: TURED combined with seminal vesiculoscopy is a suitable method for the diagnosis and treatment of persistent or recurrent haemospermia in men with EDO.

RESUMEN

The morphology of human ejaculatory ducts has not been well established. The objective of this study was to describe macroscopic and microscopic anatomy of ejaculatory ducts. We conducted a systematic review using MEDLINE, Scopus, PubMed, and Cochrane databases. Search terms were: "ejaculatory ducts," "seminal colliculus," "prostatic utricle," "anatomy," "histology," "radiology," and "embryology." We only included studies assessing adult (>18 years) humans published before November 1, 2019. We excluded studies describing pathological ducts and case reports. Independent authors extracted data using predefined criteria. Fourteen studies were included in the qualitative synthesis. Usually, the ejaculatory ducts entered the prostate by piercing the central part of its base. Most studies identified an anteromedial curve of the ducts at the outset within the prostate, their subsequent course being a straight path towards the seminal colliculus, their terminal parts diverging immediately before joining the prostatic urethra. However, the morphology of the terminal part of the ducts was inconsistent. The mean length of the ducts ranged from 1.4 to 2.2 cm. In conclusion, the luminal diameter gradually decreased as the ducts traveled towards the seminal colliculus. Ejaculatory ducts angulate anteromedially at their onset within the prostate and travel straight towards the seminal colliculus. Their terminal parts diverge immediately before joining the prostatic urethra. However, the reported dimensions of the ducts differ among studies.

RESUMEN

OBJECTIVE: To evaluate the utility of transurethral seminal vesiculoscopy with a slender ureteroscope in the treatment of severe oligoasthenozoospermia secondary incomplete ejaculatory duct obstruction (EDO). METHODS: From March 2018 to September 2018, the clinical data of 8 patients with severe oligoasthenozoospermia secondary incomplete EDO treated by the technique of transurethral seminal vesiculoscopy in the Peking University Third Hospital Reproductive Center were analyzed. Preoperative routine included semen analysis, hormone determination, transrectal ultrasonography, pelvic magne-tic resonance examination and other examinations. All the patients were diagnosed with severe oligoasthenozoospermia secondary to incomplete EDO. All the patients were operated by the same surgeon with multiple cases of experience in transurethral surgery, and 1 year follow-up was conducted to evaluate the surgical effect. RESULTS: The average age of the 8 patients was 29 years, and the average operation time was 32 min. Preoperative transrectal ultrasound indicated 6 cases of ejaculatory duct cyst or Mullerian cyst, 1 case of prostate calcification and bilateral seminal vesicle dilatation. The average maximum transverse diameter of the right seminal vesicle in pelvic MRI was 33.60 mm (24.63-42.28 mm), the average maximum transverse diameter of the left seminal vesicle was 32.85 mm (25.91-44.89 mm), the ave-rage maximum antero-posterior diameter was 27.99 mm (21.36-33.12 mm), the average maximum width of the seminal vesicle duct was 10.53 mm (5.93-19.39 mm). There were 5 cases of ejaculatory duct cyst, 2 cases of seminal vesicle hemorrhage, and 1 case of Mullerian cyst. The semen volume [(2.64±0.80) mL], the sperm concentration [(49.76±8.50)×106/mL], and the motility (grade a+b) [(25.76±6.48)%] in postoperation were significantly higher than those in preoperation [(1.46±0.50) mL, (28.78±5.17)×106/mL, and (2.88±0.93)%, P < 0.05]. Two patients conceived naturally during the follow-up of 6 months after surgery. There were no severe complications, such as retrograde ejaculation, urinary incontinence or rectal injury. CONCLUSION: The technique of transurethral seminal vesiculoscopy is safe and effective for treating severe oligoasthenozoospermia secondary to incomplete EDO. However, due to the small sample size of this study, short follow-up time, and the uncertainty in seminal vesicle surgery, it still needs to be further confirmed by long-term follow-up studies with large samples.

RESUMEN

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.

RESUMEN

Because of a general lack of knowledge regarding the precise anatomy of the seminal vesicle system, efforts to use transurethral seminal vesiculoscopy (TSV) are currently constrained. We investigated 26 normal adult male specimens. Contrast medium was injected into the seminal vesicle system in 18 specimens and the openings of the ejaculatory ducts were examined with an operating microscope. India ink was injected into the urethra in four specimens to investigate the function of the ejaculatory duct valve. Another four specimens were examined histologically to identify the anatomical relationships of the seminal vesicle system. We found that the openings of the ejaculatory ducts were covered by the ejaculatory duct valve, which could be classified into two types and acted as a one-way valve. The apex of the seminal colliculus together with the right and left openings of the ejaculatory ducts formed a shape resembling an isosceles triangle. This could be used to locate the openings of the ejaculatory ducts during TSV. The ejaculatory ducts can be classified into two types according to their course. During surgery, efforts must be made to protect the ejaculatory duct valve. During inspection or surgery, the second segment and the angles of the ejaculatory ducts, particularly in Type Ib and Type II cases, require particular attention. Clin.

RESUMEN

Prostatic adenocarcinoma remains the most common cancer affecting men. A substantial majority of patients have the diagnosis made on thin needle biopsies, most often in the absence of a palpable abnormality. Treatment choices ranging from surveillance to radical prostatectomy or radiation therapy are largely driven by the pathologic findings in the biopsy specimen. The first part of this review focuses on important morphologic parameters in needle biopsy specimens that are not covered in the accompanying articles. This includes tumor quantification as well as other parameters such a extraprostatic extension, seminal vesicle invasion, perineural invasion, and lymphovascular invasion. For those men who undergo radical prostatectomy, pathologic stage and other parameters are critical in prognostication and in determining the appropriateness of adjuvant therapy. Staging parameters, including extraprostatic extension, seminal vesicle invasion, and lymph node status are discussed here. Surgical margin status is also an important parameter and definitions and reporting of this feature are detailed. Throughout the article the current reporting guidelines published by the College of American Pathologists and the International Collaboration on Cancer Reporting are highlighted.

RESUMEN

The presence of urothelial epithelial metaplasia in a seminal vesicle is an exceptionally rare finding. We describe a unique case of urothelial metaplasia of the seminal vesicle and ejaculatory duct, found in a radical prostatectomy specimen from a patient with complex urogenital anatomy. A 70-year-old patient with organ confined (pT2) prostatic adenocarcinoma (Gleason score 3+4 = 7) had a right-sided Hutch diverticulum and a left crossed-fused renal ectopia. Although the histogenesis of urothelial metaplasia in the seminal vesicle remains unclear, in the patient presented herein it likely developed as a consequence of the previously unrecognized malformation.

RESUMEN

OBJECTIVE: To describe the methodology of transurethral seminal vesiculoscopy and the anatomy of the seminal tract, and to report a single-surgeon experience with this procedure. METHODS: A total of 38 consecutive patients with intractable macroscopic hemospermia were enrolled from January 2010 to July 2016. A 6/7.5-Fr semirigid ureteroscope was used to enter the seminal tract by one of these two approaches: through either a trans-ejaculatory duct opening or a trans-utricle fenestration. Patient characteristics and their preoperative and postoperative measurements were analyzed retrospectively. RESULTS: The success rate of transurethral seminal vesiculoscopy was 92.1%, whereas the approaching method in most patients was the trans-utricle fenestration (88.89%). A total of 34 (94.4%) transurethral seminal vesiculoscopy inspections ended with complete remission, even though nearly half of them (47.2%) only disclosed negative perioperative findings. The median period to complete remission was 4 weeks (interquartile range 4-6 weeks) after the procedure. Four patients had recurrent hemospermia, and the median time to recurrence was 21.5 (range 13-48.5) months. CONCLUSIONS: Transurethral seminal vesiculoscopy is a valuable diagnostic tool for intractable hemospermia, and also plays a therapeutic role by blocking the vicious cycle of stasis, calculi and seminal vesiculitis. More familiarity of the anatomy and enough practice would make the learning curve less steep.
