Urogenital Flashcards
what scrotal masses can you not get above
inguinoscrotal hernia or hydrocele extending proximally
Separate and cystic scrotal mass
epididymal cyst
separate and solid scrotal mass
epididymitis/ varicocele
testicular and cystic scrotal mass
hydrocele
5 testicular and solid masses
tumour, haematocele, granuloma, orchitis, gumma.
epididymal cyst
Benign cyst lesion of the epididymis.
pathology of epididymal cyst
Possibly due to obstruction of the epididymis.
2 clinical maifestations of epididymal cysts
Usually presents as a small paratesticular swelling which may be tender
Grossly appears as a thin-walled, translucent cystic lesion
management of epididymal cyst
Remove if symptomatic
hydrocele
An abnormal accumulation of fluid in the space between the two layers of the tunica vaginalis.
2 causes of hydocele
Usually caused by trauma (primary), or
A reaction to an underlying pathology such as epididymitis, orchitis or a tumour (secondary cause)
clinical manifestation of hydrocele
Scrotal swelling
3 management options for hydrocele
Can resolve spontaneously
Aspiration
Surgery: placating the tunica vaginalis/ inverting the sac
varicocele
A persistent abnormal dilation of the pampiniform venous plexus in the spermatic cord.
4 clinical manifestations of varicocele
Usually presents with nodularity on the lateral side of the scrotum
Some cause a dull ache, especially after prolonged standing or towards the end of the day
May contribute to male subfertility, as the increased flow raises the scrotal temperature and impairs spermatogenesis
Often visible as distended scrotal blood vessels.
management of varicocele
Surgery to remove if symptomatic
If left untreated can lead to infertility
what is Adenomatoid tumour
The most common benign paratesticular neoplasm.
possible locations for adenomatiod tumour
Can occur in epididymis, spermatic cord, and tunica albuginea
appearance of Adenomatoid tumour
Grossly, they are small solid, firm, grey/ white tumours which are usually <3cm
6 causes of UT obstruction
Urinary stones
Urothelial tumours
Extrinsic compression by abdominal/ pelvic masses
Prostatic hyperplasia
Urinary tract malformations
Strictures
3 common clinical manifestations of UT obstruction
Symptoms directly suggestive of obstruction (e.g. ureteric colic)
Impaired renal function
Recurrent UTIs
specific symptoms of Acute upper tract obstruction
Loin pain radiating to the groin. There may be superimposed infection, loin tenderness, enlarged kidney.
specific symptoms of chronic upper tract obstruction
Flank pain, renal failure, superimposed infection.
specific manifestations of Acute lower tract obstruction
Acute urinary retention, severe suprapubic pain, acute confusion.
specific manifestations of Chronic lower tract obstruction
Urinary frequency, hesitancy, poor stream, terminal dribbling, overflow incontinence
4 investigations for UT obstructions
Blood: U&E, creatinine, FBC and prostate-specific antigen
Urine: dipstick and MC&S
Ultrasound: hydronephrosis (swelling of the kidney due to a build-up of urine) or hydroureter = CT scan
CT scan: determines level of obstruction
treatment of Upper tract obstruction
nephrostomy or ureteric stent.
treatment of lower tract obstruction
urethral or suprapubic catheter.
complications of UT obstructions
Obstruction increases the risk of infection, stone formation, and renal damage
classification of haematuria
Visible: previously known as macroscopic, frank
Non-visible: found on dipstick/ microscopy, previously known as microscopic.
4 causes of haematuria
Malignancy (kidney, ureter, bladder)
Calculi
IgA nephropathy
Polycystic kidney disease
what causes a false haematuria positive
myoglobin triggers same dipstick reaction
investigations into cause of haematuria
Undergo urological assessment, imaging, and cystoscopy to exclude renal tract malignancy and calculi.
symptoms of testicular torsion
Sudden onset of pain in one testis, which makes walking uncomfortable
Pain in the abdomen, nausea, and vomiting are common
signs of testicular torsion
Inflammation of one testis – very tender, hot and swollen.
Testis may lie high and transversely
differential diagnoses for testicular torsion
The main one is epididymo-orchitis, and there will be symptoms of urinary infection, and more gradual onset of pain.
investigations for testicular torsion
Doppler US may demonstrate lack of blood flow to testis.
Do not delay surgical exploration
management of testicular torsion
Ask consent for possible orchidectomy + bilateral fixation
At surgery expose and untwist the testis
Benign prostatic hyperplasia
Enlargement of the prostate gland due to an increase in cell number.
pathology of Benign prostatic hyperplasia
Androgens are critical in the development of BPH, more specifically increased levels of dihydrotestosterone locally in the prostate.
Current evidence suggests that increased oestrogen levels in blood induce androgen receptors in prostate tissue and stimulate hyperplasia
6 symptoms of Benign prostatic hyperplasia
Frequency
Urgency
Nocturia
Hesitancy
Poor flow
Terminal dribbling
4 differential diagnoses for BPH
Overactive bladder
Prostatitis
Prostate cancer
UTI
4 investigations for BPH
GS+ FL= digital rectal exam
PSA test
Frequency chart
Urine dipstick
lifestyle changes for BPH
Avoid caffeine, alcohol, to reduce urgency.
Void twice in a row to aid emptying
drugs for BPH
useful in mild disease, and while awaiting surgery
α-blockers are 1st line e.g. Tamsulosin
surgery for BPH
Transurethral resection of prostate
Transurethral incision of the prostate
Retropubic prostatectomy
4 complications of BPH
Urinary retention
Recurrent UTIs
Bladder stones
Obstructive nephropathy
renal carcinoma
A malignant epithelial tumour arising in the kidney.
5 symptoms of renal carcinoma
Loin pain
Abdominal mass
Anorexia
Malaise
Weight loss
how are renal carcinoma cases usually picked up
About half of all cases present with painless haematuria
Most of the remained is picked up incidentally on imaging
A small proportion presents with metastatic disease
investigations for renal carcinoma
FL=
Abdominal/pelvis ultrasound, bloods: raised RBC, raised calcium, raised LDH
GS=
CT chest/abdo/pelvis
management of renal carcinoma
Radical nephrectomy.
Cryotherapy and radiofrequency ablation is an option for patients unfit or willing to undergo surgery
what is Nephroblastoma
AKA Wilm’s tumour
A malignant childhood renal neoplasm
presentation and prognosis of nephroblastoma
Presents with abdominal mass and haematuria
Most tumours are of low stage with an excellent prognosis with treatment
what are urothelial carcinomas
A group of urothelial neoplasms arising in the urothelial tract.
clinical manifestations of bladder cancer
Haematuria – painless
LUTS
Recurrent UTIs
Voiding irritability
4 investigations for bladder cancer
FL=
urinalysis for microscopy and culture (haematuria), bladder USS
GS=
Flexible cystoscopy and biopsy
management of T1 bladder cancer
Diathermy via transurethral cystoscopy/ transurethral resection of bladder tumour
management of T2-3 bladder cancer
Radical cystectomy is the gold standard.
Radiotherapy gives worse survival rates than surgery but preserves the bladder.
management for T4 bladder cancer
Palliative chemo/radiotherapy.
Chronic catheterisation and urinary diversions may help to relieve pain
