“…Stone size was recorded as the largest diameter measured on either the lateral or ventrodorsal radiographic view, although these measurements may not reflect the true stone size because of radiographic magnification; however, Byl et al found that there was no difference in mean stone size among radiography, cystography, and CT, although there was a difference between these imaging modalities compared with stone measurement on abdominal ultrasound. As such, ultrasound reports were not used in our study to document stone size.…”

“…While most dogs were imaged with radiography, a subset were imaged with ultrasonography. Ultrasonographic images overestimate cystolith size, and this might have introduced minor inaccuracies in urolith measurements 16 . Treatment regimens were also not standardized, as they were selected by the clinician managing the case at the time.…”

Background Medical dissolution of struvite uroliths in dogs is commonly recommended, but data on success rates and complications are limited. Objectives To evaluate the efficacy of medical dissolution for suspected struvite cystoliths in dogs. Animals Fifty client‐owned dogs fed a therapeutic dissolution diet, with or without administration of antimicrobials, for treatment of suspected struvite cystoliths. Methods Single institution, retrospective case series. Medical records were reviewed for dogs with at least 1 follow‐up visit. Dissolution success, complications, and possible predictors of success were evaluated. Results Full dissolution of cystoliths was achieved in 58% (29/50) of dogs within a median of 35 days (range, 13‐167). Of 21 dogs without success, 7 each had partial dissolution, no dissolution, or undetermined outcome. Uroliths containing >10% nonstruvite mineral were common in the nonsuccess group (11/16 analyzed). Maximum urolith diameter, number of uroliths, and baseline urine pH did not differ significantly between dogs with and without success. Dissolution was more likely in dogs receiving antimicrobial therapy (OR = 16.3, 95% confidence interval 1.9‐787.4, P = .002). Adverse events occurred in 9 dogs (18%); urethral obstructions were the most common, but 3 of 4 dogs with this complication were obstructed on presentation, before trial initiation. Conclusions and Clinical Importance Results support a medical dissolution trial for dogs with suspected struvite cystoliths. If no reduction in urolith size or number occurs by 1 month, a nonstruvite composition is likely, and alternative interventions should be considered. Dogs presenting with urethral obstructions should not be considered candidates for medical dissolution.

“…Für Urat-, Cystein- sowie Calciumphosphatsteine gilt das nicht. Ihr röntgenologischer Nachweis ist mit einer 25–27 % falsch negativen Quote behaftet, während diese Quote bei der Sonografie für alle Harnblasensteine, kompositions- und größenunabhängig, nur 3,4–6,5 % beträgt 29 . Röntgenologisch lassen sich aber insbesondere bei röntgendichten Materialien (Konkremente, Steine) Anzahl und Lage in der klinischen Routine sicherer bestimmen.…”

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.
