Summary

Dynamic transrectal echography effectively diagnoses bladder neck diseases like BPH and prostate carcinoma. This noninvasive imaging method reveals key morphological features for accurate disease identification and post-surgical assessment.

Area of Science:

  • Urology
  • Medical Imaging
  • Diagnostic Techniques

Background:

  • Dynamic transrectal echography is a primary, safe, and noninvasive method for evaluating bladder neck diseases during micturition.
  • Understanding morphological features of various bladder neck conditions is crucial for diagnosis and management.

Purpose of the Study:

  • To identify specific echographic features for different bladder neck diseases, including benign prostatic hyperplasia (BPH), carcinoma, and Marion disease.
  • To evaluate morphological changes after prostate surgery.

Main Methods:

  • Examination of 32 patients with diagnosed bladder neck conditions.
  • Utilizing dynamic transrectal echography during micturition.
  • Analysis of morphological images in patients with BPH, carcinoma, Marion disease, and post-prostatectomy.

Main Results:

  • Prostate enlargement in BPH can obstruct the urethra, making it difficult to visualize in a single sagittal plane.
  • Prostate carcinoma may initially be asymptomatic on urodynamic studies; invasion and stenosis present as thin, elongated, irregular urethral profiles.
  • Bladder neck sclerosis diagnosis is aided by a posterior "beak" at the internal meatus, urethral dilatation, and a positive Stop-Test.
  • Post-surgery, complete relaxation of the internal and external sphincters is observed, contributing to continence.

Conclusions:

  • Dynamic transrectal echography provides excellent imaging for diagnosing bladder neck diseases.
  • Distinct echographic features aid in differentiating conditions like BPH, prostate carcinoma, and bladder neck sclerosis.
  • The study highlights the utility of this technique in assessing post-surgical anatomical and functional changes.
