ABSTRACT. Nephrectomy is the complete removal of the kidney and ipsilateral ureter and usually it is performed through a midline laparotomy for the treatment of end-stage unilateral kidney disease. Indications for performing nephrectomy may include: renal and ureteral neoplasms, persistent renal haematuria, serious renal trauma associated with or without avulsion of renal pedicle, end-stage hydronephrosis, single renal cysts associated with renal disease, polycystic kidney disease associated with pyelonephritis, renal parasites, renal or perirenal abscessation, chronic end-stage pyelonephritis and renal disease associated with ectopic ureter. Normal function of the contralateral kidney is a prerequisite for performing nephrectomy. The presence of azotaemia or persistent isosthenuria is a contraindication for nephrectomy. Nephrectomy for pyelonephritis may not consistently resolve the infection in the remaining kidney. Preoperative evaluation of renal function in animals undergoing nephrectomy would ideally include determination of glomerular filtration rate using renal nuclear scintigraphy. However, in clinical practice, excretory urography is performed for the assessment of renal function. Nephrotomy is a limited surgical incision through the dorsal renal surface to remove nephroliths, to explore the pelvis for polyps and neoplasms and to identify causes of renal haematuria. Nephrotomy is reported not to significantly affect renal function in normal dogs and cats. Indications for nephrotomy associated with the presence of nephroliths may include hydronephrosis and hydroureter associated with renal pelvic obstruction, recurrent infection resistant to conservative treatment, progressive nephrolith enlargement and deterioration of renal function. Pyelolithotomy for calculus removal may only be used when the renal pelvis and the proximal ureter are markedly dilated.Keywords: cat, dog, nephrectomy, nephrotomy ΠΕΡΙΑΗΨΗ. Νεφρεκτομή ονομάζεται η ολική αφαίρεση του νεφρού και του σύστοιχου ουρητήρα που γίνεται συνήθως διαμέσου μέσης λαπαροτομής. Η νεφρεκτομή στο σκύλο και τη γάτα διενεργείται για την αντιμετώπιση μη ανατάξιμης βλάβης του νεφρού. Ενδείξεις για την εκτέλεση της νεφρεκτομής αποτελούν : α) τα νεοπλάσματα του νεφρού και του σύστοιχου ουρητήρα, β) η επίμονη ιδιοπαθής νεφρική αιματουρία, γ) η βαριά κάκωση του νεφρού με ή χωρίς απόσπαση του νεφρικού μίσχου από την πύλη, δ) η υδρονέφρωση τελικού σταδίου, ε) οι μονήρεις νεφρικές κύστεις που συνοδεύονται από διαταραχή της νεφρικής λειτουργίας, στ) ο πολυκυστικός νεφρός με πυελονεφρίτιδα, ζ) τα παράσιτα του νεφρού, η) το νεφρικό ή περινεφρικό απόστημα, θ) η βαριά πυελονεφρίτιδα και ι) η νεφρική βλάβη λόγω έκτοπου ουρητήρα. Η ομαλή λειτουργία του ετεροπλάγιου νεφρού αποτελεί προϋπόθεση για την εκτέλεση της νεφρεκτομής. Αντένδειξη για την εκτέλεση της νεφρεκτομής αποτελεί η παρουσία αζωθαιμίας ή επίμονης ισοσθαινουρίας.

“…[13][14][15] Cats with nephroliths often have compromised renal function, and it is unclear whether concurrent renal disease is a result of nephrolithiasis, whether renal disease predisposes to nephrolith formation, or whether these are independent events. 4,5 Since concurrent renal disease is often present, nephrotomy has the potential to result in a further decline in kidney function by direct trauma to nephrons, disruption of vasculature, edema and fibrosis from the inflammatory response, or tissue ischemia from temporary occlusion of renal arterial blood flow.…”

Effect of Nephrotomy on Renal Function and Morphology in Normal Cats

Objective:To assess effects of bisection nephrotomy on renal function, size, and morphology in cats over a period of 12 weeks. Study Design:Controlled, randomized, blinded experiment. Sample Population:Ten adult female cats. Methods:Glomerular filtration rate (GFR), as determined by quantitative renal scintigraphy using Results:No significant differences in mean GFR and kidney size of the operated versus unoperated kidneys were observed at any time period. Individual GFR and renal size of all except one of the cats remained within normal limits. Two additional cats had evidence of transient ureteral obstruction in the immediate post-operative period. No significant histologic abnormalities were observed in any biopsy. Conclusions:Bisection nephrotomy in normal cats did not adversely affect renal function or morphology over the three month post-operative period. Clinical Relevance:Bisection nephrotomy can be safely performed in normal feline kidneys without causing a significant deleterious effect on renal function. Studies in animals with pre-existing renal insufficiency are needed to insure no adverse effects would occur in clinical cases where this surgical procedure is warranted.

“…[1][2][3] In recent years, the pig kidney has been considered the best urologic experimental model because of its anatomic resemblance to the human kidney. 4,5 For many institutions, however, swine procurement and their maintenance as well as management in the laboratory setting are difficult, so that other animals have been used in research on the urinary system.…”

A systematic study of the morphometry and the collecting system of the canine kidney is presented and compared with previous findings in humans. Renal measurements (kidney length, width, and thickness) were recorded. In addition, 110 three-dimensional endocasts of the kidney collecting system were produced and studied. Anatomic details, important to research and surgical training in endourology, were observed and recorded in canine kidneys. Dogs whose height was more than 70 cm at the withers presented similar kidney measurements to those found in the adult human. The collecting system consisted only of a renal pelvis with a variable number of recesses around its perimeter. The dog kidney is not a good model for experimental studies that consider the morphology of the collecting system. Kidneys from dogs taller than 70 cm, however, might be useful as a model in experimental studies in which renal volume is an important aspect, such as shockwave lithotripsy and endourology.

The Effect of Nephrotomy on Renal Function and Morphology in Dogs

Abstract: Neither intersegmental nor bisection nephrotomy adversely affected GFR. As intersegmental nephrotomy requires additional surgical manipulation and time, bisection nephrotomy is the technique of choice for nephrotomy in dogs.
