[Etiology, risk factors, and outcome of urinary tract infection].

Objectives: To determine the incidence and variety of microorganisms of positive urine culture in patients of intensive care units of Kaunas University of Medicine Hospital and to estimate the risk factors for colonization, development of urinary tract infection, and outcome during the period of 2003-2004.

Material And Methods: We retrospectively reviewed patients with a positive urine culture with or without clinical symptoms of urinary tract infection admitted to an intensive care unit.

Results: The growth of microorganisms was determined in urine of 82 (3.

Metal type of the femoral stem in total hip arthroplasty.

Objective: To compare the influence of two different cemented stems each made of different alloys on survival and outcome.

Material And Methods: We analyzed 341 total hip replacements performed in 1998-2001. Two types of prostheses were implanted.

Total hip replacement for the treatment of femoral neck fractures. Long-term results.

Objective: To evaluate the outcome of total hip replacement after femoral neck fractures and analyze implant survival rates, complication rates, and mortality after surgery.

Material And Methods: We analyzed 135 primary hip replacements and 8 revision hip replacements performed in 1991-2003 years. Femoral neck fracture was the diagnosis for all primary hip replacements.

[Hip revision arthroplasty (long-term results)].

Objective: To evaluate the risk factors after total hip replacement arthroplasty for rerevision and to analyze complications after hip revision surgery.

Material And Methods: We obtained data from 117 hip revisions and 12 hip rerevision arthroplasties performed in 1992-2001 in the Department of Orthopedics of Klaipeda Hospital. Special forms were filled in for every patient who participated in the study.

[Early results of total ankle arthroplasty].

Unlabelled: Objective of the study was to evaluate total ankle arthroplasty as the treatment of choice for ankle arthritis; to analyze variables' influence upon early results after total ankle arthroplasty; and to determine early and late postoperative complications and the ways to avoid them.

Material And Methods: We evaluated clinical results of 18 patients (out of 23 operated patients), for whom total ankle replacement was performed in 1998-2003. Uncemented Scandinavian Total Ankle Replacement (WLink, Germany) endoprosthesis was used in all cases.
