Urolithiasis in 68 Horses

Abstract

Medical records of 68 horses with urolithiasis were examined. Calculi were in the bladder in 47 horses, urethra in 11 horses, kidneys in 15 horses, and ureter in two horses. They occurred at several sites in six horses. Common clinical signs included hematuria, altered micturition (pollakiuria, dysuria, urinary incontinence), and tenesmus. Weight loss, possibly attributable to chronic renal failure and colic, was associated more commonly with renal and ureteral calculi. Weight loss also occurred in 13% of horses with cystic calculi only. In male horses, most cystic calculi were removed by perineal (ischial) urethrotomy under epidural anesthesia. Although there were few surgical complications with urethrotomy, seven of 15 horses with follow-up suffered recurrent urolithiasis.

First Report of Urolithiasis in a Donkey in Western Kordufan, Sudan

“…Some authors believe that urinary system infections occur less frequently in the equine than in other species such as dogs, cats, swine, bovines, ovine and caprine [2,3]. The prevalence of urolithiasis in horses has been estimated at 0.11% over a 20-year period [4]. Out of 68 horses reported with urolithiasis, 59.7% had calculi in bladder and 24% had urethral calculi while 12.6% had renal calculi, and 3.7% had ureteral calculi [4].…”

The factors that help predispose a horse for urolith formation are prolonged urine retention, incomplete bladder emptying, increased mineral content of the water as well as decreased water intake.…”

“…Bei Pferden kommt Urolithiasis mit einer Inzidenz von 0,11 % im Vergleich zu anderen Spezies relativ selten vor, wobei vor allem männliche Tiere, insbesondere Wallache betroffen sind (Laverty et al 1992). Als Prädilektionsstellen für die Lokalisation eines Harnsteins kommen die Blase (60% der Fälle), die Harnröhre (24%), Harnleiter (4%) und das Nierenbecken (12%) in Frage (Laverty et al 1992).…”

Es wird angenommen, dass Stuten eigentlich ebenso häufig wie männliche Pferde erkranken, allerdings auf Grund der Beschaffenheit der Harnröhre die Urolithen leichter aus dem Harntrakt herausgespült werden können.…”

“…Es wird angenommen, dass Stuten eigentlich ebenso häufig wie männliche Pferde erkranken, allerdings auf Grund der Beschaffenheit der Harnröhre die Urolithen leichter aus dem Harntrakt herausgespült werden können. Im Durchschnitt erkranken die Pferde in einem Alter von 10,2 ± 6,5 Jahren (Laverty et al 1992). …”
