“…Eventually the patency of the urethra could have been restored using a cystoscopic-guided laser lithotripsy, as recently described in a female guinea pig. 34 In contrast to the published case, the non-crystalline structure of the malleable proteinaceous granules in this guinea pig might oppose fragmentation under laser therapy. The sinusoid course of the urethra in this male guinea pig might additionally render the urethroscopic approach more difficult.…”

A foreign body cystitis in a 1.5-year-old male guinea pig with treatment-resistant stranguria and haematuria was diagnosed by ultrasonographic examination. A sedge leaf (Carex species) was identified as the causing agent by sequencing of nuclear ribosomal DNA (ITS1) and a chloroplast marker (trnL-trnF) from the leaf obtained on postmortem examination. The eventual mechanism of migration of the plant leaf into the bladder was investigated. A concomitant fungal lower urinary tract infection with Candida albicans was diagnosed by cultural means and DNA sequencing. Firm granules composed of inflammatory secretions blocked the urethra and interfered with diagnostic and therapeutic approaches. To the authors’ knowledge this is the first report of foreign body cystitis in a small rodent, which should be on the differential list of therapy-resistant lower urinary tract disease in guinea pigs.

“…24 It is generally accepted that medical management of urolithiasis is often not successful in guinea pigs 7 ; therefore, surgical intervention, cystoscopic removal, or lithotripsy is often indicated. 7,[25][26][27] Our findings indicated that surgery should not be considered as a risk factor for nonsurvival. Instead, urolith retrievability, sex, and age of the patient and concurrent disease must be considered when formulating a treatment plan.…”

OBJECTIVE To investigate risk factors, clinical features, and prognostic indicators in guinea pigs with urolithiasis. ANIMALS 158 guinea pigs with urolithiasis. PROCEDURES Medical records of an exotics animal specialty service were searched, identifying guinea pigs with urolithiasis. Signalment, clinical data, and outcomes were recorded. Variables of interest were analyzed for statistical associations with outcome. RESULTS Overall, 54.4% (86/158) of animals survived to discharge. Median survival time was 177 days. Females (53.2%; 84/158) were more common than males (46.8%; 74/158). Males were presented younger (mean age, 3.64 years) than females (4.41 years). In 81 of 154 (52.5%) cases, animals were presented with primary urinary concerns, while 73 (47.5%) presented for nonurinary primary concerns. Females more commonly presented with distal urinary tract urolithiasis (63/84; 75%) but fared better overall with a longer median survival time (1,149 days) than males (59 days). Surgical intervention was not a risk factor for nonsurvival; however, increased age (> 4.1 years), male sex, anorexia, weight loss, and lower rectal temperature (< 37.2 °C) on presentation were associated with nonsurvival. Reoccurrence was noted in 13.9% (22/158) of cases, at an average of 284 days. CLINICAL RELEVANCE Urolithiasis should always be considered a differential diagnosis for any unwell guinea pig. In particular, distal urinary tract urolithiasis should be considered in females. A poorer prognosis was associated with older, male guinea pigs, and those displaying anorexia, weight loss, and hypothermia. The need for surgical intervention should not confer a poorer outcome. Further studies are needed to determine specific risk factors and identify possible preventative measures.

“…Die Urolithiasis ist ein gut bekanntes, nicht so seltenes Leiden bei Minischweinen 4 , 5 , 6 , 7 , 8 , 23 , 24 , 25 . Die Harnsteinbildung und deren Ansammlung in Blase und Harnröhre dürfte auch bei Nutzschweinen, die zur Zucht und Mast gehalten werden, vergleichbar hoch sein 4 , 26 .…”

“…In der Diagnostik weisen meist die klinischen Symptome sowie erhöhte Werte der harnpflichtigen Substanzen Kreatinin und Harnstoff im Serum auf eine Obstruktion der ableitenden Harnwege hin 8 , 9 , 11 , 16 , 17 , 27 , 28 . Allerdings trifft das bei Minischweinen, wie auch im vorliegenden Fall, selten zu 8 , 23 , 24 , da keine Azotämie bestand. Anzunehmen ist, dass Minipigs bei Auffälligkeiten jeder Art dem Tierarzt wie ein „companion animal“ zeitnah vorgestellt werden und sich bis dahin keine Azotämie entwickeln konnte.…”

ZusammenfassungEin 10-jähriges kastriertes, männliches Minischwein wurde aufgrund eines Tenesmus vesicae mit Anurie vorgestellt. Begleitsymptom war eine Tachypnoe. Röntgenologisch waren zahlreiche Harnsteine in Blase und Urethra nachweisbar. Über die Harnröhre konnte nicht katheterisiert werden, sodass eine Notfallzystostomie mit Einlegen eines Ballonkatheters durchgeführt wurde. Trotz Blasenspülung gelang es nicht die Harnröhrensteine so auszuspülen. Deswegen wurde ein präpubisches Urethrostoma angelegt. Das Tier erholte sich vollständig und setzt seither problemlos Urin über die urethrale Fistel ab. Prophylaktische Maßnahmen der Urolithiasis beinhalten unter anderem eine ausreichende Wasseraufnahme, eine ausgewogene Fütterung und balancierte Futterzusammensetzung sowie die Gewährleistung eines physiologischen Urin-pH-Werts.
