A 19-year-old nullipara developed uremia due to acute
pyelonephritis
in the 30th week of pregnancy, necessitating hemodialysis within one week of onset of clinical infective symptoms. Almost daily prophylactic hemodialyses (7 in all) were performed. BUN and serum creatinine levels were maintained below 75 mg/100 ml and 12 ml/100 ml respectively, and the patient's weight was kept constant until delivery in the 32nd week of pregnancy. A live healthy child of 1.7 kg was born with a length of 39 cm and a normal neurologic examination. After 10 hemodialyses,
polyuria
set in and the maternal BUN and serum creatinine levels were within normal ranges 3 weeks after delivery. The importance of close cooperation between gynecologist and internist is stressed.

A metabolic study was performed in 28 patients with bilateral recurrent calcium-containing renal staghorn calculi and chronic
pyelonephritis
("obstructive nephropathy"). Fourteen had normal GFR and 14 mild renal insufficiency. Ten normal subjects were used as controls. Under basal conditions,
polyuria
and negative sodium balance were commonly observed in patients with obstructive nephropathy and normal renal function. After an acute acid load (NH4Cl) an acidifying defect, i.e. high values for urine pH and reduced excretion of titratable acid and ammonium, was observed in 64% of patients with normal GFR and in 71.4% of those with renal insufficiency. During intravenous infusion with neutral sodium phosphate, the urine pH changed little but the rate of excretion of titratable acid increased in direct proportion to that of urinary phosphate in both groups of patients. These results, associated with the finding of normal blood pH in almost all patients, lead to the conclusion that an incomplete Type 1 or "distal" renal tubular acidosis is a frequent complication of obstructive nephropathy secondary to bilateral nephrolithiasis. The anatomical abnormalities of renal tubules and collecting ducts and the superimposed interstitial nephritis might be the pathogenetic factors responsible for the acidifying defect and for the impairment in sodium and water conservation.

Hydronephrosis and
pyelonephritis
were diagnosed in a 2-year-old Limousin bull. Salient historical and clinical observations included weight loss, anorexia, intermittent colic,
polyuria
, polydypsia, and an ammoniacal breath odor. Intravenous treatment with fluids and antibiotics did not induce a favorable response. An anomalous vas deferens was observed on postmortem examination. The vas deferens ended in a blind polyp that protruded into the lumen of the urethra. This polyp may have caused chronic intermittent obstruction, predisposing to the hydronephrosis and
pyelonephritis
.

Primary disorders of water balance (central diabetes insipidus, congenital nephrogenic diabetes insipidus, and psychogenic polydipsia) should always be considered in the differential diagnosis of
polyuria
and polydipsia. In general, animals with these disorders have only one laboratory abnormality, a low urine specific gravity. The more common causes of
polyuria
and polydipsia (eg, hypercalcemia, chronic renal insufficiency,
pyelonephritis
, hyperadrenocorticism), in most instances, have specific and obvious abnormalities associated with the complete blood count (CBC), serum chemistry profile, and urinalysis. However, in some cases, a low urine specific gravity may initially be the only abnormality in these more common ruleouts. The workup for
polyuria
and polydipsia, especially in those cases with normal or near normal blood work, can be tedious, time consuming, confusing, and not without significant patient morbidity. This chapter will focus on the problems associated with diagnostic testing used to evaluate animals with disorders of water balance.

Diagnostic possibilities of selective examination of renal urine particularly collected under medicamentous
polyuria
conditioned by the administration of Lazix were studied in latent bacteriuria. By means of separate collection of renal urine against the background of
polyuria
it was possible additionally to detect bacteriuria in 1/3 of the patients, to record increase in the intensity of the index in almost half of the patients with renal bacteriuria and, in 1/4 of them to detect, in renal urine, the aetiological agent absent from bladder urine. The latter circumstance not only has a diagnostic significance but also plays a certain role in the selection of medicamentous therapy in chronic
pyelonephritis
. In addition to traditional bacteriological methods, filtration through membrane filters was used to isolate and identify microflora in the urine. By means of this method it is possible to detect extremely low bacteriuria which cannot be established by any other method.

Escherichia coli-induced
pyelonephritis
was studied in untreated alloxan-diabetic rats, insulin-treated diabetic rats, glucose water-drinking (diuresing) nondiabetic rats, and tap water-drinking (nondiuresing) nondiabetic rats following injection of E. coli either into the emptied urinary bladder, into the left kidney, or intravenously. For prevention of an ascending infection in the right kidney, the right ureter was ligated and transected immediately prior to bladder or intrarenal inoculation. These experiments established that in normal rats ascending renal infection alone occurred following introduction of small inocula into the bladder--and then only when facilitated by diuresis. In diabetic rats both ascending and hematogenous renal infection occurred following introduction of small inocula into the bladder. Insulin treatment that reduced hyperglycemia also reduced glycosuria and restored urinary antibacterial activity against small inocula of E. coli but only partially reduced
polyuria
and prevented hematogenous but not ascending infection. Thus, hyperglycemia was probably the major factor promoting hematogenous renal infection, whereas
polyuria
--and therefore vesicoureteral reflux--was the major factor promoting ascending infection.

Recently, drug
polyuria
has found wide application in diagnosis and treatment: to detect latent urinary insufficiency, to assess functional performance of the contralateral (unaffected) kidney in nephrolithiasis and calculous
pyelonephritis
, to stimulate elimination of fragments of the disintegrated concrement, to check up suture impermeability after surgical repair of the urinary tracts, to outline afunctional zone in hydronephrosis. Clinical experience gives grounds for use of saluretics at certain stages of pyelolithotomy for mobilization of intrarenal pelvis and its dissection, removal of the calculus and subsequent suturing of the intrarenal pelvis. Therapeutic
polyuria
can also facilitate ureterolithotomy.

Primary disorders of water balance (central diabetes insipidus [DI], nephrogenic DI, and psychogenic polydipsia) should always be considered in the differential diagnosis of
polyuria
and polydipsia. In general, animals with these disorders have only one laboratory abnormality: a low urine specific gravity. In most instances, the more common causes of
polyuria
and polydipsia (e.g., hyperadrenocorticism, chronic renal failure,
pyelonephritis
, pyometra) have specific and obvious abnormalities associated with the complete blood cell count, the serum chemistry profile, and urinalysis. In some cases, however, a low urine specific gravity may be the only abnormality associated with these more common findings. The workup for
polyuria
and polydipsia can be tedious, time-consuming, expensive, confusing, and not without significant patient morbidity, especially in those cases with normal or near-normal blood work. This article focuses on the diagnostic approach and problems associated with diagnostic testing in patients with disorders of water balance.

A four-month-old male Labrador retriever was presented for
polyuria
, polydipsia and persistent euglycaemic glucosuria. On referral, diagnostic tests demonstrated abnormal fractional excretions of electrolytes, increased urinary excretion of selected amino acids, mild renal tubular acidosis and mild proteinuria, indicating renal tubular dysfunction.
Pyelonephritis
was suspected and potentiated amoxycillin was administered. On re-evaluation at six months of age, the dog was no longer polyuric or polydipsic and the metabolic abnormalities associated with the tubulopathy had resolved. Transient Fanconi's syndrome has not previously been reported in small animals. This report demonstrates the potential for recovery of function in cases presenting with renal tubulopathies.

A 5-year-old castrated male Golden Retriever was evaluated for
polyuria
, polydipsia, and progressive regurgitation thought to be a result of bacterial
pyelonephritis
and megaesophagus. Bacteriologic culture of urine failed to yield clinically relevant growth, and results of a urine sediment examination were normal. With time, intention tremors and progressive neurologic dysfunction were also observed. At necropsy, a diagnosis of cryptococcal disease was confirmed histologically and immunohistochemically. Findings in the dog of this report were indicative of nephrogenic diabetes insipidus with
polyuria
and polydipsia caused by cryptococcal
pyelonephritis
. Neurologic manifestations of systemic cryptococcus infection included megaesophagus, esophageal hypomotility, and regurgitation attributed to localization of cryptococcal organisms in the brain stem in the region of the dorsal motor nucleus of the vagus nerve. To the authors' knowledge, this is the first report of
polyuria
secondary to cryptococcal
pyelonephritis
.
