Urinary tract infections (UTIs) are the most common infections among chronic renal failure (CRF) and end stage renal disease patients (ESRF). They are very common in the early post transplant period due to surgery, bladder catheters and immunosuppression. Many organisms are implicated including gram positive, gram negative, unusual pathogens and fungal UTIs. Prevention and early diagnosis of UTIs is important in CRF and renal transplant population.
In this work 100 hemodialysis patients, 50 predialysis CRF patients and 20 renal transplant recipients were studied.
All patients had a complete urine examination, direct smears, Zeihl Neelson's stain, colony count, culture on blood, cled, sabaraud dextrose agar and bbl septic shock with antimicrobial susceptibility, serum antibodies for Chlamydia, and urinary identification and isolation for mycoplasma and urea plasma using special culture media. Incidence of UTIs was 80% (16/20) among renal transplanted patients in the 1st 3 months post transplant, with e.coli as the most common organism followed by staphylococci and Candida, only one patient had urea plasma a 2nd had atypical mycobacterial infection whereas a 3rd was positive for TB. in the predialysis group 35 out of 50 patients had UTIs with incidence of 70%, again e.coli and klebsilla was the most common, with dephteroids and staph epidermidis commonly encountered. Whereas in hemodialysis group the incidence was 63% (63/100) with a wide range of causative microorganisms.
Antimicrobial susceptibility, patterns of drug resistance, rate of recurrence, correlations of these findings with different clinical data and their influence on the clinical outcome of the patient and graft will be discussed.
