A positive dipstick for leucocyte esterase is 96% specific for >10 wbc/mm3

A bacterial culture with > 10^5 has 95% probability of representing infection.

Use of blood cultures in does not change management when urine culture is taken

All patients with pyelonephritis require follow-up USS of kidneys.

Запитання 3

Acute simple cystitis in male patients – Augmentin or trimethoprim for 14 days.

Dysuria with < 10 3 organisms grown on culture failed to improve on trimethoprim – doxy.

Запитання 4

Which is incorrect regarding acute renal failure?

варіанти відповідей

In pre-renal failure the ratio of urea: creatinine is increased above normal.

Post-renal obstruction is an uncommon cause of ARF.

The most common cause of renal ARF is acute tubulointerstitial nephritis.

Urinalysis with microscopic hematuria, pyuria, and presence of granular, epithelial and RBC casts is consistent with acute glomerulonephritis.

In renal ARF the urine Na is > 10mmol/l and osmolality < 350.

Запитання 10

Which is incorrect regarding CAPD peritonitis?


варіанти відповідей

Gram stain will be positive in approx 10-40% of culture positive bags

Staph aureus is the most common organism isolated.

Antibiotics are not needed parentally usually.

Vancomycin as a one off 2 grams to CAPD bags is all that is needed for proven gram positive infection.

Cell count in bags must be > 100 leucocytes with > 50% neutrophils

Запитання 11

Which is incorrect of renal transplant patients?


варіанти відповідей

Identical twin donor and recipient, require no immunosuppression

Graft rejection may present with graft tenderness, decreased urine output and increased creatinine.

Infection is the most common cause of morbidity and mortality in the early stages, with 80% developing infection in the first year.

Rejection of graft over 1 year post transplant indicated chronic rejection which results in progressive loss of renal function.

Cyclosporine toxicity rarely is a complication due to predictable levels.
