ULTRASONOGRAPHY

ULTRASONOGRAPHY

1. Definition: Ultrasonography, also known as ultrasound, is a diagnostic imaging technique that uses high-frequency sound waves to create images of structures within the body.

2. Importance of ultrasonography in urology:

   • Non-invasive
   • No radiation exposure
   • Low cost
   • Real-time imaging
   • Widely available

3. Role in diagnosis of renal, ureteric, bladder, and prostate diseases:

   • Renal diseases: kidney stones, hydronephrosis, renal cancer, and polycystic kidney disease
   • Ureteric diseases: ureteric stones, ureteric strictures, and ureteropelvic junction obstruction
   • Bladder diseases: bladder stones, bladder cancer, and interstitial cystitis
   • Prostate diseases: prostate cancer, prostatitis, and benign prostatic hyperplasia

4. Detection of stones, masses, hydronephrosis, and congenital anomalies:

   • Stones: kidney stones, ureteric stones, and bladder stones
   • Masses: kidney masses, prostate masses, and bladder masses
   • Hydronephrosis: kidney swelling due to urine backup
   • Congenital anomalies: kidney malformations, ureteric malformations, and bladder malformations

5. Pathology:

   • Renal pathology: kidney stones, kidney cancer, and kidney cysts
   • Ureteric pathology: ureteric stones, ureteric strictures, and ureteropelvic junction obstruction
   • Bladder pathology: bladder stones, bladder cancer, and interstitial cystitis
   • Prostatic pathology: prostate cancer, prostatitis, and benign prostatic hyperplasia

6. Types of ultrasonography:

   • 2D ultrasonography: creates 2D images of structures within the body
   • 3D ultrasonography: creates 3D images of structures within the body
   • Doppler ultrasonography: measures blood flow within vessels
   • Contrast-enhanced ultrasonography: uses contrast agents to improve image quality

7. Causes of renal, ureteric, bladder, and prostate diseases:

   • Renal diseases: kidney stones, high blood pressure, diabetes, and kidney cancer
   • Ureteric diseases: ureteric stones, ureteric strictures, and ureteropelvic junction obstruction
   • Bladder diseases: bladder stones, bladder cancer, and interstitial cystitis
   • Prostate diseases: prostate cancer, prostatitis, and benign prostatic hyperplasia

8. Clinical features of renal, ureteric, bladder, and prostate diseases:

   • Renal diseases: flank pain, hematuria, and hypertension
   • Ureteric diseases: flank pain, hematuria, and urinary retention
   • Bladder diseases: urinary frequency, urinary urgency, and hematuria
   • Prostate diseases: urinary frequency, urinary urgency, and erectile dysfunction

9. Investigations for renal, ureteric, bladder, and prostate diseases:

   • Renal function tests
   • Urine analysis
   • Urine culture
   • Ultrasound
   • CT scan
   • MRI

10. Complications of renal, ureteric, bladder, and prostate diseases:

    • Renal complications: kidney failure, kidney stones, and kidney cancer
    • Ureteric complications: ureteric obstruction, ureteric strictures, and ureteropelvic junction obstruction
    • Bladder complications: bladder cancer, interstitial cystitis, and bladder stones
    • Prostate complications: prostate cancer, prostatitis, and benign prostatic hyperplasia

11. Management and treatment of renal, ureteric, bladder, and prostate diseases:

    • Medical treatment: antibiotics, pain medications, and anti-inflammatory medications
    • Surgical treatment: nephrectomy, ureterostomy, and prostatectomy
    • Conservative treatment: dietary changes, fluid intake, and lifestyle modifications

12. Blood supply and nerve supply of the urinary tract:

    • Renal blood supply: renal arteries
    • Renal nerve supply: renal plexus
    • Ureteric blood supply: ureteric arteries
    • Ureteric nerve supply: ureteric plexus
    • Bladder blood supply: bladder arteries
    • Bladder nerve supply: bladder plexus
    • Prostatic blood supply: prostatic arteries
    • Prostatic nerve supply: prostatic plexus

13. Clinical anatomy of the urinary tract:

    • Renal anatomy: kidney location, kidney size, and kidney shape
    • Ureteric anatomy: ureteric location, ureteric size, and ureteric shape
    • Bladder anatomy: bladder location, bladder size, and bladder shape
    • Prostatic anatomy: prostate location, prostate size, and prostate shape
