Altered microbiota profile in seminal vesicles of men presenting with refractory hematospermia. Mol Biol Rep 2023; 50:2381-2389. [PMID: 36585555 DOI: 10.1007/s11033-022-08139-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 11/21/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND Currently, no recognized evidence is known about the bacterial communities found within seminal vesicles (SV) of men presenting with refractory hematospermia. METHODS AND RESULTS Fifteen male patients with refractory hematospermia or anejaculation were enrolled, and 15 SV-Infection (SV-In) samples from SV with hemorrhage and/or stones, 11 SV-Control (SV-C) samples from SV with non-infection, and 14 Urine (Urine) samples from posterior urethra were obtained via transurethral seminal vesiculoscopy. Then the high-throughput 16 S rRNA gene sequencing method was performed to characterize the microbiota profile. Finally, a total of 1535 operational taxonomic units (OTUs) were found, 1295 OTUs were shared across three groups, 7 OTUs, 45 OTUs, and 48 OTUs were unique to SV-C group, SV-In group, and Urine group, respectively. The 5 top bacterial phyla (mean relative abundance) in all samples were Firmicutes (52.08%), Bacteroidetes (21.69%), Proteobacteria (12.72%), Actinobacteria (9.64%), and Fusobacteria (1.62%), the 5 top bacterial genera in all samples were Bacteroides (9.13%), Lactobacillus (5.38%), Bifidobacterium (5.35%), Faecalibacterium (5.10%), and Allobaculum (3.34%), of which Bifidobacterium had the highest level in SV-C samples and had a significant difference (P < 0.05) across all groups. Differential analysis showed genera Leuconostoc and LachnospiraceaeFCS020group were identified as biomarkers in the SV-In microbiota. CONCLUSION Altered microbiota composition in seminal vesicles is related to refractory hematospermia in men, and the distribution of genus Leuconostoc or LachnospiraceaeFCS020group within seminal vesicles may interact with hematospermia. This study provides clues for the diagnosis and treatment of this urologic disorder.

[PMID: 35789209 PMCID: PMC9255724 DOI: 10.1371/journal.pone.0268314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 06/14/2022] [Indexed: 11/30/2022] Open
Abstract
We have summarized our experience regarding transurethral seminal vesiculoscopy (TUSV) and analyzed both its recurrence status and the risk factors for recurrence. From January 2010 to December 2020, 48 patients with intractable hemospermia received successful TUSV at Taichung Invalids General Hospital. Upon analysis of the intraoperative findings, the five-year disease-free Survival rates (DFS) were 74.1% in the no calculus group compared to 37.1% in the calculus group with a significant difference (log-rank p = 0.015), 75.0% in the no hemorrhage or no blood clot group compared to 43.2% in the hemorrhage or blood clot group with significant difference (log-rank p = 0.032). Univariate analysis showed intraoperative calculus (p = 0.040; HR: 2.94, 95% CI: 1.05–8.21) to be significantly associated with recurrence (p < 0.05). Patients with intractable hemospermia who were diagnosed with stones or blood clots found during TUSV experienced a higher rate of hemospermia recurrence.

Han H, Lei HE, Zhang XD, Tian L. Magnetic resonance imaging compared to ultrasound as the preferred method for diagnosing intractable haematospermia. Andrologia 2021; 53:e14054. [PMID: 33955038 PMCID: PMC8244118 DOI: 10.1111/and.14054] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 03/05/2021] [Accepted: 03/06/2021] [Indexed: 01/12/2023] Open
Abstract
We aimed to evaluate and compare the clinical diagnostic values of magnetic resonance imaging (MRI) and ultrasound in patients with intractable haematospermia. We performed a retrospective review of 23 patients with intractable haematospermia who were diagnosed with seminal vesicle haematocele and/or calculi by transurethral seminal vesiculoscopy (TSV). Patients’ demographics, disease durations, operative times, and MRI and transrectal ultrasound (TRUS) results were recorded. McNemar's test was used to compare the positive diagnostic rates of MRI and TRUS. All patients had undergone preoperative seminal vesicle MRI and TRUS to identify the aetiology of the haematospermia. The average age and disease duration were 39.3 years and 24.1 months, respectively. The mean operative time was 81.1 min. The positive result rates for MRI and TRUS were 95.7% (22/23) and 39.1% (9/23), respectively. Compared with TRUS, MRI had a significantly higher preoperative positive diagnostic rate (p < 0.01). These results suggest that MRI should be considered as a method for diagnosing intractable haematospermia in patients when TRUS findings are negative or inconclusive.

Application of ultrasound-guided seminal vesicle radiography combining CT three-dimensional reconstruction technique in transurethral seminal vesiculoscopy. Andrologia 2020; 52:e13845.

Abstract
For the treatment of ejaculatory duct obstruction, transurethral seminal vesiculoscopy (TSV) is the most common method, but the success rate is much lower than studies that have reported. So we developed a new ultrasound-guided seminal vesicle radiography (UGSVR) combining CT three-dimensional reconstruction (CT-TR) technique to improve the success rate of TSV. Between June 2018 and November 2019, 32 patients were enrolled and randomly assigned to two groups: experimental group (UGSvR combining CT-TR) and control group (standard evaluation). Baseline information, including age, smoking history and body mass index (BMI), was compared preoperatively. Surgical parameters included success rates (SR), surgical time (ST), catheter days (CD), length of hospital stays (HS) and complications were compared between groups. There were no statistically significant differences in baseline data between the two groups (all p > .05). There were no significant differences in the CD, HS and complications between the two groups (all p > .05), but the differences in ST and SR were statistically significant (p < .05). In conclusion, this new technique of UGSvR combining CT-TR was achieving a satisfactory increase in the success rate of TSV, while not increasing the incidence of complications, compared to normal evaluation before TSV operation.
