Area of Science:

Urology
Medical Diagnostics

Background:

Hematospermia (blood in ejaculate) is a common urological concern requiring identification of underlying causes.
Prostatic utricle translucent membranes are a potential cause of hematospermia, necessitating accurate diagnostic tools.
Current diagnostic methods lack sufficient predictive power for preoperative planning.

Purpose of the Study:

To develop and validate a novel nomogram for predicting translucent membranes in the prostatic utricle among hematospermia patients.
To identify independent risk factors associated with prostatic utricle translucent membranes.

Main Methods:

A cohort of 284 hematospermia patients was divided into training (198) and validation (86) sets.
Multivariable logistic regression analysis identified risk factors for prostatic utricle translucent membranes.
A predictive nomogram was constructed and evaluated using ROC curves, calibration curves, and decision curve analysis (DCA).

Main Results:

Age, disease duration, seminal vesiculitis history, and seminal vesicle dimensions were identified as independent risk factors.
The developed nomogram demonstrated strong predictive capability and accuracy.
Decision curve analysis confirmed significant clinical utility and net benefits for the nomogram.

Conclusions:

The novel nomogram effectively predicts the presence of prostatic utricle translucent membranes in hematospermia patients.
Clinical application of this nomogram can aid in precise diagnosis and individualized treatment strategies.
This tool enhances preoperative planning and potentially improves patient outcomes for hematospermia.
