Successful treatment of seminal vesicle calculi and prostatic utricle calculi by transurethral seminal vesiculoscopy

Abstract

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.

Magnetic resonance imaging compared to ultrasound as the preferred method for diagnosing intractable haematospermia

“…Patients with intractable haematospermia showed high‐intensity signals on T1WI and low‐intensity, or middle‐ and high‐intensity signals on T2WI, which indicated the presence of fresh or old haemorrhages in the seminal vesicles (Figure 1b and c). These findings were consistent with those of previous reports (Li et al., 2012; Li et al., 2013; Liao et al., 2019; Song et al., 2020). The condition can be used as an absolute indication for TSV.…”

“…For patients with intractable haematospermia, an increasing number of studies have suggested that TSV is a safe and effective method of diagnosis and treatment that can both significantly alleviate haematospermia and treat seminal vesicle calculi (Chen et al., 2018; Liao et al., 2019; Miao et al., 2020; Song et al., 2020; Tian et al., 2018; Zaidi et al., 2019). However, whether all patients with intractable haematospermia need to undergo TSV can be investigated by actively using MRI or ultrasound to evaluate the aetiology of the haematospermia before surgery.…”

Application of seminal vesiculoscopy on the treatment of seminal vesiculitis

“…With the development of minimally invasive technology, more and more patients hope to receive minimally invasive techniques such as endoscopy, laparoscopy, or robotic surgery for disease diagnosis and treatment. Transurethral seminal vesicle microscopy has developed rapidly as a new endoscopic technique (25). Seminal vesiculoscopy has its unique advantages in the treatment of SV, especially for blood sperm caused by minimal lesions (26).…”
