“…Although the incidence of bladder calculi accounts for only 5% of all urinary calculi, it is the most common urinary complication in patients with NB following SCI and is primarily due to limited fluid intake, urinary stasis, bladder outlet obstruction, anatomical abnormalities, catheterization, or recurrent UTI [ 1 , 2 , 6 ]. Bladder calculi in patients with NB following SCI are mainly associated with UTI, and a variety of foreign bodies, such as Foley balloon fragments, hair, and silk sutures, can be involved in the formation of bladder calculi as nidus [ 13 - 15 ]. However, studies on how infections lead to the formation of calculi are lacking [ 5 ].…”

Purpose: To develop a rat model of bladder calculi in the neurogenic bladder following spinal cord injury (SCI) and assess bacterial communities within the biofilm of bladder calculi using denaturing gradient gel electrophoresis (DGGE).Methods: The silk tied to a small segment of the Teflon IV catheter was implanted through the urethra into the bladder of rats with SCI induced by T9 laminectomy. After 6 months, the rats were sacrificed and their bladder calculi were collected by opening the bladders through the low-midline incision. Genomic DNA was extracted from the biofilm of bladder calculi followed by DGGE to obtain bacterial DNA. The DNA sequences were compared and analyzed using BLAST (Basic Local Alignment Search Tool) to identify bacteria.Results: After placing silk nidus in the bladder for 6 months, all 6 rats developed bladder calculi. According to DGGE analysis, Pseudomonas aeruginosa was the most dominant strain, while Clostridium sp. and Lactobacillus sp. were relatively dominant strains within the biofilm of bladder calculi in the rats with SCI.Conclusions: DGGE analysis showed various microorganisms in the biofilm of calculi arising from a neurogenic bladder rat model. This research design can be the basis for clinical studies and may be applied to calculi in patients with neurogenic bladder following SCI.

“…Typical components of urine like calcium, oxalate, uric acid, and phosphate make up most of the calculi formed in the urinary system. Repeated urinary tract infections caused by urea-splitting bacteria commonly Proteus mirabilis which leads to an alteration in the pH of the urine is a common cause of struvite stones [ 5 ]. A history of suprapubic pain dysuria, weak urinary stream and hematuria may be helpful in the diagnosis of stones in the urinary tract but are not pathognomonic since tumors, and other lesions in the bladder may cause similar signs and symptoms.…”

The urinary bladder stones are formed due to urinary retention, obstruction to the flow of urine commonly caused by enlargement of the prostate in males, urinary tract infections, and foreign body. The urinary bladder stones are usually found in males, and its presentation in females is a rare entity. Recurrence of urinary tract stones is commonly due to either repeated urinary tract infections or any metabolic condition. We present a case of a 75-year-old female patient who had a history of urinary tract infection and bladder stone formation and was operated for the 16th time recently for removal of her bladder stones.

“…Foreign bodies involved in the creation of bladder calculi include Foley balloon fragments [4], silk sutures [5], fragments of clothing [6], intrauterine devices [7], and hair nidus [8]. Another source of formation of foreign-body bladder stones derives from frequent use of clean, intermittent catheterization.…”

“…Foreign body stones of the urinary bladder are mostly composed of a mixture of struvite and carbonate apatite, which are components of stones due to infection. Alteration of urine pH due to infection by urea-splitting bacteria, typically Proteus mirabilis, is an established causative factor in the development of these stones [4]. The presence of a foreign body increases the susceptibility to urinary tract infection and the accumulation of crystalline and organic components.…”

Bladder calculi rarely form spontaneously and are usually a manifestation of an underlying pathologic condition of the lower urinary tract, including voiding dysfunction, urinary infection, obstruction, or foreign body retention. However, a ruptured Foley balloon-induced bladder stone is an unusual complication of an indwelling Foley catheter. We report a case of spinal cord injury with paraplegia and bladder stone induced by a fragment of a ruptured Foley balloon. The bladder stone and the Foley balloon fragment were successfully removed by cystoscopy. The stone was composed of calcium oxalate and calcium phosphate. We report this unusual case to raise awareness that it is important to check the integrity of the Foley catheter after removal of the tube.
