Summary
This report details the first percutaneous transretropubic prostate biopsy in a patient with a blocked anus. This novel technique successfully diagnosed prostate cancer when standard methods were impossible.
Area of Science:
- Urology
- Oncology
- Medical Imaging
Background:
- Transrectal ultrasound-guided prostate biopsy is standard but not feasible in patients with anal strictures.
- Prostate cancer screening involves prostate-specific antigen (PSA) testing and digital rectal examination.
Purpose of the Study:
- To describe a novel percutaneous transretropubic prostate biopsy technique.
- To demonstrate the feasibility of prostate biopsy in patients with contraindications for transrectal approaches.
Main Methods:
- A 74-year-old male with a history of colectomy and severe anal stricture presented with elevated PSA.
- A percutaneous transretropubic prostate biopsy was performed under transabdominal ultrasound and computed tomography guidance.
- Pathological analysis confirmed prostatic adenocarcinoma.
Main Results:
- The percutaneous transretropubic prostate biopsy was successfully completed.
- Prostatic adenocarcinoma was diagnosed.
- This represents the first documented instance of this biopsy technique.
Conclusions:
- Percutaneous transretropubic prostate biopsy is a viable alternative when transrectal biopsy is not possible.
- This technique allows for prostate cancer diagnosis in challenging anatomical situations.

Imaging Studies V: Intravenous Urography and Retrograde Pyelography
171
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Urologic Endoscopic Procedure: Cystoscopic Examination
379
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
