<p>Fourniers gangrene vs nec fascitis</p>
<p>Fourniersis nec fas affecting perinieum</p>
<p>Bulbar urethra rupture mechanism</p>
<p>Straddle type injury eg bike</p>
<p>Bulbar urethra rupture sx</p>
<p>Triad:</p>
<p>- perineal haematoma</p>
<p>- urinary retension</p>

<p></p>
<p>Sx of membranous urethral rupture</p>
<p>Perineal haematoma<br></br>
| High prostate on PR</p>

<p>Ix for urethral rupture</p>
<p>ascending urogram</p>
<p>Mx of urethral rupture</p>
<p>Surgical suprapubic catheter</p>
<p>Where does urine collect as a result of injury to membranobulbar urethral junction</p>
<p>Anteriorly into scrotal tissue (fascial condensation prevents posterior/lateral spread)</p>

<p>Penile fracture mx</p>
<p>Immediate surgery:</p>
<p>Fracture sutured and urethra repaired over a catheter</p>
<p>Renal artery thrombosis post transplant presentation</p>
<p>Sudden loss of urine output</p>
<p>Renal artery thrombosis post-transplant mx</p>
<p>Thrombectomy within 1 hr (ideally within 30 mins)</p>
<p>Renal artery stenosis presentation post-transplant</p>
<p>Over several months,</p>
<p>HTN</p>
<p>Slight deterioration of renal function</p>
<p>Renal artery stenosis mx</p>
<p>Stent</p>
<p>Treatment of hydrocele in adults</p>
<p>Lords or Jaboulay operation via scrotal approach</p>

<p>Treatment of hydrocele through in children</p>
<p>Ligation of patent processus vaginalis through an inguinal approach</p>
<p>Renal stone that is inherited</p>
<p>Cysteine</p>
<p>Autosomal recessive</p>
<p>Disorder of transmembrane cystine transport leading to reduced absorption</p>
<p>Proteus UTI risk</p>
<p>Struvite stone formation</p>
<p>Urine acidity with urate stones</p>
<p>acidity</p>
<p>Urine acidity with struvite stone</p>
<p>Alkaline</p>
<p>Which stones can you see on x ray</p>
<p>Calcium phosphate (most Radiodense)</p>
<p>Calcium oxalate (Radiodense)</p>
<p>Struvite (Slightly Radiodense)</p>
<p>Cystine (Relatively Radiodense)</p>
<p>Uric acid (Radiolucent)</p>

<p>Renal stone size and mx options</p>

<p>Ureteric stone size and mx options</p>

<p>In which patients would you not do watchful waiting for renal stones</p>
<p>Ureteric obstruction</p>
<p>Prvs abnormality eg horseshoe</p>
<p>Prvs renal trasnplant</p>
Treatment for infected ureteric obstruction
Nephrostomy tube
or
Ureteric stent via cystoscopy (retrograde)
Shockwave lithotripsy contraindications
Pregnant
Significant vessel calcification
Phimosis def
Inability to retract the foreskin

Paraphimosis def
Prolonged retraction of the foreskin proximal to glans leads to oedema and inability to retract foreskin

Paraphimosis treatment
Compression of glans to reduce oedema
If not, dorsal slit followed by delayed circumcision
By what age does foreskin allow complete retraction
16
How is cremasteric reflex different in torsion of testis and torsion of testicular hydatid
Cremasteric reflex is preserved in torsion of the appendage
But lost in torsion of the testis
