This report describes a 40-year-old man with an unusual form of granulomatous pyelonephritis, associated with nephrolithiasis, resulting in end-stage kidney disease and right pretransplant nephrectomy. The kidney specimen contained a staghorn calculus and showed chronic inflammation with confluent caseating granulomas and multinucleated giant cells, resembling renal tuberculosis. However, neither tubercle bacilli nor other microorganisms were demonstrated in the renal tissue or in urine cultures. Because these findings do not support a tuberculous etiology of the granulomatous pyelonephritis, we conclude that this patient had a pseudotuberculous reaction as a consequence of nephrolithiasis.

Thirty patients with partial of total staghorn calculi or pyelic calculi greater than 30 mm were treated by extracorporal piezo-electric lithotripsy (PEL) exclusively with an EDAP LT 01 lithotripter equipped with an ultrasound localisation system. Nineteen patients had a pyelic calculus and the others a partial (n = 9) or total (n = 2) staghorn calculus. All patients first underwent extracorporal lithotripsy (ECL). None of the patients received IV sedation or anesthesia. When fragmentation of the calculus was observed after the first session, a double J stent was inserted before the second ELC session. Before the first session, urine samples were sterile in 18 of the 30 patients; 12 of the 30 patients presented major distention of the urinary tract. Results were analysed to identify factors affecting results of this type of treatment. Patients whose calculus had completely disappeared on plain films three months after the first session were considered to be cured clinically and radiologically (14/30 = 46%). Seven patients (23.3%) were clinically cured (absence of pain and sterile urine) but there were residual fragments (1 to 3 fragments less than or equal to 4 mm). No fragmentation was obtained after the first session in 9 patients (30.7%) (1 total staghorn, 8 pyelic calculi). The mean number of sessions was 5 (range 1-15). Only 10% of the patients (3/30) presented a complication: 2 steinstrasses and 1 acute pyelonephritis. 83% of the patients without urinary tract distention and 55% of the patients whose urines were initially sterile were cured.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of diffuse xanthogranulomatous pyelonephritis of the kidney with an associated renocolic fistula is reported. Computed tomography demonstrated typical findings with an enlarged poorly functioning kidney with multiple near-water-density masses replacing the renal parenchyma surrounding a central staghorn calculus. A mottled gas collection within the renal parenchyma was secondary to a renocolic fistula rather than a pyogenic abscess.

Some guidelines for the use of lasers in renal surgery are presented. The carbon dioxide laser was successfully used in 9 patients with diverse renal pathology (staghorn calculus, 4 patients; renal tumor, 3 patients; congenital arteriovenous (A-V) fistula, 1 patient; segmental chronic atrophic pyelonephritis, 1 patient) as an excisional tool, allowing us to reduce intraoperative blood loss, decrease operating time, and preserve the functional integrity on the remaining renal segment. This modality appears to be a safe addition to the urologic armamentarium, when used as an excisional tool in renal surgery.

A case of mucinous adenocarcinoma of the renal pelvis occurring in association with staghorn calculus and severe pyelonephritis is reported. The incidence and aetiopathogenesis of this neoplasm is briefly discussed.

The ultrasonic findings of three patients with surgically confirmed xanthogranulomatous pyelonephritis are presented. All of the involved kidneys were markedly enlarged, had a large central echogenic area, and demonstrated an increased parenchymal anechoic pattern. The appearance correlated well with the other radiographic and gross pathologic findings. While this appearance was fairly distinctive, it is anticipated that there will be some difficulty in distinguishing this entity from simple hydronephorsis, especially in conjunction with staghorn calculus. It is also anticipated that focal xanthogranulomatous pyelonephritis will have an atypical appearance.

A case is reported of the simultaneous occurrence of renal carcinoma with staghorn calculus, perinephric abscess, and xanthogranulomatous pyelonephritis in the same kidney, with subcutaneous abscess of the thigh as the initial presentation. The coexistence of these diseases in the same kidney would seem to be important since they are frequently confused with each other.

A 34-year-old woman who 14 years previously had undergone a left nephrotomy for nephrolithiasis complained of pain in the left renal fossa which was reddened and painful on percussion. She had a fever of 38.2 degrees C. C-reactive protein was raised to 80 mg/l, the white cell count to 14,620/microliters (83% neutrophils). Protein and white cells were found in the urine together with a significant number of E. coli on urine culture. Plain film of the abdomen showed a staghorn calculus and ultrasonography demonstrated renal enlargement with a possible paranephritic abscess. The computed tomography diagnosis was xanthogranulomatous pyelonephritis, on the basis of renal enlargement, staghorn calculus, hypodense areas with typical density values (10-15 Hounsfield units), contrast enrichment and extrarenal extension of partly phlegmonous partly fused-together inflammatory changes. The abscessing parts were drained under computed tomography control. Starting 7 days pre-operatively the patient had been receiving ciprofloxacin (0.4 g daily) intravenously. A nephrectomy had to be performed subsequently. Antibiotic treatment was discontinued 2 weeks later and she was discharged symptom-free. The diagnosis of diffuse xanthogranulomatous Pyelonephritis was confirmed by histological examination of the surgical specimen.

A patient presented with a reno-cutaneous fistula revealing a xanthogranulomatous pyelonephritis secondary to staghorn calculus. Total nephrectomy was necessary because of renal destruction. This treatment allowed closure of the fistula and a good clinical result.

Calculi in a noncommunicating or excluded calix may be associated with infection, pain, and focal renal damage. Some authors have recommended removal of these calculi and reestablishment of the pelvicaliceal communication, either by dilation of the infundibulum or creation of a neoinfundibulum, in order to prevent recurrent stone formation and infection. Herein, we report two patients with stones in a completely excluded calix, one after repeated courses of shockwave lithotripsy for a staghorn calculus and the other after recurrent pyelonephritis. The combined approach is especially helpful if the examiner is in doubt about the anatomy (true calix v caliceal diverticulum) or if a natural infundibulum cannot be identified by antegrade endoscopy.
