Background: The objective of this study is to determine in a case series (four patients) how calcified deposits in renal papillae are associated with the development of calcium oxalate monohydrate (COM) papillary calculi. Methods: From the recently collected papillary calculi, we evaluated retrospectively patients, subjected to retrograde ureteroscopy, with COM papillary lithiasis. Results: The...

X-ray powder diffraction was used to study the phase composition of human renal calculi. The stones were collected from 56 donors in Vitória, Espírito Santo state, southeastern Brazil. An XRD phase quantification revealed that 61% of the studied renal stones were composed exclusively of calcium oxalate 34% formed only by calcium oxalate monohydrate COM and 27% presents both monohydrate and dihy...

OBJECTIVES To report our experience of diagnosis and multimodal management of urolithiasis in renal transplantation. PATIENTS AND METHODS From January 1995 to December 2012, 953 patients underwent renal transplantation in the Kidney Transplant Unit of Treviso General Hospital. Ten (10%) of them developed urinary calculi and were referred at our institution. Their mode of presentation, investi...

Percutaneous nephrostolithotomy (PCNL) constitutes first line therapy for large and complex renal calculi. However, retained calculi generated by intracorporeal lithotripsy remain a concern because of their potential for growth and future symptoms. Liberal use of flexible nephroscopy identifies residual calculi and increases stone free rates. However, historically the sensitivity of radiographi...

BACKGROUND Staghorn calculi are well-established risk factors for recurrent urinary tract infections (UTIs) and subsequent renal deterioration. Less commonly, long-term urothelial irritation from a calculus may also pose a risk of malignant transformation. CASE PRESENTATION A 77-year-old male with multiple medical comorbidities presented with a chronic right renal pelvic staghorn calculus and...

BACKGROUND Bryophyllum pinnatum, commonly known as Pattharcaṭṭa, is used traditionally in ethnomedicinal practices for the treatment of kidney stone and urinary insufficiency. AIM The present study evaluated the effect of Bryophyllum pinnatum on ethylene glycol (EG)-induced renal calculi in rats. MATERIALS AND METHODS Renal calculi were induced in rats by administration of 0.75% EG in drink...

Urinary stone is a worldwide disease and percutaneous nephrolithotomy (PCNL) is the most commonly used operation for staghorn calculi. Research indicated that SFR for staghorn calculi in one stage of PCNL showed 50%-91% results, under standard operation, standard instrument and professional treatment route. The present study aimed to explore the clinical factors of stone free rates (SFR) after ...

Thirty patients (16 men and 14 women) with cystine urinary stones were treated by extracorporeal shock wave lithotripsy (Dormer HM-3) from December 1984 through October 1989. The average patient age was 35.2 years with a range of 14 to 59 years. Seventy per cent of these subjects had had previous open surgical operations for stones. The cases consisted of 7 ureteral stones and 37 renal stones, ...

RATIONALE Primary renal pelvis squamous cell carcinoma (SCC) is an extremely rare neoplasm. In many patients, the SCC was associated with renal calculi. PATIENT CONCERNS A 61-year-old male presented with intermittent pain at the left lumbar region for 3 days. The PET/CT images demonstrated increased F-FDG uptake in the upper pole of the left kidney and left renal hilar lymph nodes. DIAGNOSE...

Urolithiasis in renal transplantation is uncommon. In the most of cases stones formation appear to form “de novo” after renal transplantation, although some studies suggest that the calculi are more often transplanted with the graft to the recipient. The etiology of stone formation in renal transplantation is multifactorial. Surgical factors, urinary tract infections and metabolic anomalies cau...
