Urinary Tract Infections (UTIs) are a highly significant and complex clinical challenge in patients with CKD and, most critically, in recipients of a renal transplant. These infections encompass a range of microbial invasions affecting various parts of the urinary system, including the bladder, urethra, and, more critically, the transplanted kidney itself.

UTIs hold unique clinical significance in renal transplantation due to the complex interplay of immunosuppressive regimens, altered urinary tract anatomy, and the lifelong implications for graft function and patient well-being.

Acute renal colic is a sudden, severe flank pain radiating from the costovertebral angle to the groin or testicle, usually caused by urinary tract obstruction from a stone and often accompanied by nausea and vomiting. Urolithiasis affects about 1 in 11 people in the U.S. and occurs when crystals move from the kidney and obstruct urinary flow, typically in the ureter. This leads to hydroureteronephrosis, the main cause of renal colic.
