Study Notes

Urethra Mucosa

Lining of the urethra facilitates urine passage and prevents leakage during voiding.
Musculature surrounding the urethra, including the external urethral sphincter, allows voluntary control over urine release.

Contraindications

Management of acute urinary tract infections such as prostatitis, urethritis, and epididymorchitis is critical.
Septic conditions pose significant risks and should be avoided.

Technique

Local, venous, or spinal anaesthesia can be employed for procedures involving the urethra.
Lubrication is applied to minimize mucosal trauma.
French catheter scale is often utilized during procedures.

Resectoscope

Instrument similar to a cystoscope designed for performing resections with electrical currents.

Indications for Resection

Used in cases of benign prostate hyperplasia (BPH) and bladder carcinoma.
Effective for conditions like ureterocoele requiring resection.

Urethrotomes

Surgical tools designed for precise incisions in the urethra, typically featuring a narrow, sharp blade.
Enable clear visualization of the kidney's interior for stone fragmentation and removal.

Flexible Nephroscope

Facilitates antegrade manipulations, especially in accessing calyces and smaller spaces in the kidney.

Upper Urinary Tract Drainage Methods

Nephrostomy involves using tubes to carry urine from the kidney to an external drainage bag.
Ureteral stents (Double J Stents) allow urine to bypass obstructions, ensuring continuous flow from the kidney to the bladder.
