Urethral calculi: presentation and management

Abstract

RESULTSAcute retention of urine occurred in 78% of patients, urethral anatomical pathology in 6% and posterior urethral calculi in 88%. The urethral stones, solitary in each patient, consisted of calcium oxalate in 86%, struvite in 6%, mixed stones in 4%, calcium phosphate in 2% and uric acid in 2%. A methodical approach to therapy was used which aimed to clearly define the circumstances in which a given procedure was used, and the resulting success rate. CONCLUSIONThe common belief that most urethral calculi in patients in developing countries originate from the bladder does not seem to be generally applicable. Urethral anatomical pathology does not seem to be a necessary condition for most of these calculi.

A very rare case report of giant calculus in bulbar urethra

“…4 Urethral stones affect children more often than adults because of higher prevalence of bladder stones in lower age group. 5 Predisposing factors for formation of urethral stones include the presence of urethral stricture, urethral diverticulum, hypospadias and meatal stenosis. 6,7 It is found to be rare in females due to smaller urethra and lesser prevalence of vesical calculi.…”

A Rare Condition of Multiple Urethral Stones With Meatal Stenosis

“…(5) The frequency of urethral abnormalities associated with these calculi has been estimated to be as high as 56% of patients. (2,4,6) Kamal et al examined 51 patients with urethral stones and found 86% of patients with calcium oxalate stones, 6% with struvite stones and 2% with uric acid stones. (1) As in the present case, the calcium oxalate calculi likely originated in urethra or got obstructed in urethra due to meatal stenosis.…”

Multiple urethral calculus misdiagnosed as urethral stricture: The role of imaging in unknotting the confusion

“…Failure to diagnose impacted urethral stone can lead to long term urethral damage, renal insufficiency and incontinence. 1,2,3,4,5,6 The aim of this case report therefore is to highlight and emphasize the role of imaging in the prompt diagnosis and management of urethral calculi.…”

“…The secondary calculus produces a sudden obstruction either complete or partial and necessitates immediate intervention. 5,6 Diagnosis of urethral stone may be challenging as symptoms can be non-specific and not every imaging modality used in the evaluation of nephrolothiasis includes lower genitofemoral tract. Failure to diagnose impacted urethral stone can lead to long term urethral damage, renal insufficiency and incontinence.…”
