Seminal vesicle calculi are a rare entity that may present with hematospermia, painful ejaculation, or urinary complaints. We present a case of a 40-year-oldmale with complaints of hematospermia, ejaculatory pain, and perineal discomfort in the last five years. A 7 mm left seminal vesicle calculi were diagnosed by magnetic resonance imaging (MRI), and a laparoscopic robot-assisted vesiculectomy was performed. All the complaints improved completely after treatment. Seminal vesicle lithiasis should be kept in mind when evaluating patients with hematospermia and ejaculatory pain. Transrectal ultrasound (TRUS) and magnetic resonance imaging are the best radiology techniques to diagnose this kind of lithiasis. Different surgical treatments can be used to treat these calculi, depending on the size and location of the calculi and the surgical experience of the surgeon.

Background: Similar to other secretory organs, the male spermatic ducts may develop calculi. However, this condition is described as rare in literature and usually affects the seminal vesicles. As far as we know, no cases of calculi in the ampulla of the ductus deferens have been published so far. Patients with seminal vesicle calculi usually complain of hematospermia, painful ejaculation, perineal or testicular discomfort or pain, and often experience significant impairment of quality of life. Case Presentation: We present a case of a 39-year-old patient who presented himself in an external urologic practice with recurrent hematospermia and painful ejaculation. According to the diagnosis of a seminal vesicle calculus of 1 cm in length on the right side, the patient underwent a transurethral vesiculo- and ampulloscopy with a semirigid ureteroscope whereby the stone could be located in the ampulla of the ductus deferens and removed in toto. Conclusion: Lithiasis should be kept in mind when examining patients with hematospermia and ejaculation pain. Transurethral ampulloscopy is an efficient, safe, and minimally invasive method for stone removal from the ampulla of the ductus deferens.

To investigate the outcomes of transurethral seminal vesiculoscopy (TSV) for the treatment of seminal vesicle calculi (SVC), prostatic utricle calculi (PUC) and combination of them, a retrospective review on 27 patients with SVC and/or PUC who complained of intractable haematospermia was conducted. Patient demographics, disease duration, operation time, stone location and complications were recorded. The calculi in the seminal vesicle and/or prostatic utricle were removed by holmium laser lithotripsy and/or basket extraction. The stone composition was determined in 19 of 27 patients using Infrared spectroscopy. The average age and disease duration of patients were 39.4 years and 23.1 months respectively. The mean operative time was 78.5 min. We detected SVC, SVC and PUC, and PUC in 59.3% (16/27), 33.3% (9/27) and 7.4% (2/27) patients respectively. The stones were mainly composed of calcium oxalate dehydrate (COD), carbonate apatite (CA), COD and calcium oxalate monohydrate (COM), CA and magnesium ammonium phosphate, CA and COM, and COD and uric acid in 42.1% (8/19), 21.1% (4/19), 15.8% (3/19), 15.8% (3/19), 5.3% (1/19) and 5.3% (1/19) cases respectively. No intraoperative and post-operative complications were noted. These results suggested that SVC and PUC can be diagnosed and treated using TSVs.

UNASSIGNED: Seminal vesicle (SV) stones are a rare, and thus readily misdiagnosed condition in practice. Understanding the etiology, diagnosis, and management are crucial to guide a urologist\'s care, and are provided in this literature review.
UNASSIGNED: The inclusion criteria for the literature search, using the search engines MEDLINE® and PubMed was conducted using a combined query of \"seminal vesicle stone\" and the following keywords: calculi, hematospermia, calcification, and transrectal ultrasound (TRUS).
UNASSIGNED: The etiology of SV stones is currently unknown where majority of the patients present with having painful ejaculation and hematospermia. However, clinicians have reported potential etiologies by categorization as an inflammatory or non-in-flammatory. A majority of the previous cases had shown multiple stones being present in the SV duct system that are typically diagnosed through radiological examination such as TRUS, MRI, or plain radiographs. Amongst the many imaging approaches, TRUS remains the primary imaging diagnoses of SV calculi. Transurethral seminal vesiculoscopy has shown to be used in an abundant of the case reports to be an ideal surgical approach for managing small SV stones. In regard to larger stones, a transperitoneal laparoscopic protocol is proper.
UNASSIGNED: The current imaging techniques have increased the case reports and diagnosis of SV calculi; however, more research is warranted for understanding the pathogenesis of the formation of SV stones. An optimal management of the extraction of SV stones depends on a number of factors such as size and location.

To compare the clinical features of seminal vesicle calculi(SVC) versus posterior urethral haemangioma(PUH) to assist urologists in differentiating and diagnosing the causes of haematospermia. Patients with SVC or PUH were included. Patient age, disease duration, hospital stay, operation time, symptoms, surgical approach, pathological results and postoperative complications were recorded. A total of seven patients with SVC and 15 patients with PUH involved have an average age of 34.1 and 44.5 years separately. Patients with SVC complained of recurrent haematospermia; patients with PUH complained of recurrent haematospermia and urethral opening bleeding after sexual arousal. SVC manifested as a dark red blood-semen mixture with ejaculation pain and no blood clots; the condition could improve after anti-infective treatment. PUH manifested as no visible blood-semen mixture, bright red semen with blood clots and no ejaculation pain; the condition did not respond to anti-infective treatment. SVC was treated with holmium laser lithotripsy under a transurethral seminal vesiculoscopy. PUH was treated with transurethral resection and fulguration. Postoperative follow-up showed that the clinical symptoms gradually disappeared, with no postoperative complications. Both SVC and PUH can result in recurrent haematospermia. Therefore, urologists should treat haematospermia differently according to the cause.
