Cryoglobulins are immunoglobulins that undergo reversible precipitation at low temperatures. They can induce systemic vasculitis, characterized by purpuric cutaneous lesions, arthritis, peripheral neuropathy, hypocomplementemia and glomerular disease. Renal pathology reveals membranoproliferative glomerulonephritis, with particularly intense mesangial cell proliferation and infiltration by macrophages, associated with intracapillary thrombi. This renal disease presents as a nephritic syndrome, with heavy proteinuria, haematuria severe hypertension and rapidly progressive kidney failure that can lead to end-stage renal disease...

Introduction Transurethral resection of the prostate (TURP) is considered the gold standard surgical treatment for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia. The number of TURPs performed has declined significantly over the last three decades owing to pharmaceutical therapy. TURP data from a single institution for the years 1990, 2000 and 2010 were compared to assess the difference in performance. Methods A retrospective analysis was undertaken of all patients who underwent TURP between January and December 2010...

A 12-year-old girl born to third-degree consanguineous parents presented with recurrent episodes of haematuria for 8 months in association with peri-orbital and lower limb oedema for 20 days. There was no jaundice, hepatomegaly or neurological abnormality at presentation. An older brother had died following jaundice at 10 years of age. Urinalysis showed multiple dysmorphic erythrocytes without proteinuria and there was leucopenia, thrombocytopenia and hypo-albuminaemia (23 g/L). C3 component of complementaemia was low and anti-nuclear antibodies and anti-double-stranded DNA antibodies were strongly positive by immunofluorescence...

Urethral caruncle (UC) is a benign fleshy outgrowth at the urethral meatus. It was first described by Samuel Sharp in 1750 and occurs mainly at the posterior lip of the urethra, and the exact aetiology is still uncertain. More often it was seen in the postmenopausal women, and only few cases are reported in young girls. Patients may be asymptomatic and could find this as an incidental finding or they may present with symptoms such as dysuria, bleeding per vagina, haematuria, a mass protruding through vagina, and acute retention of urine...

BACKGROUND: Lassa fever is a viral haemorrhagic disease endemic to west Africa. No large-scale studies exist from Nigeria, where the Lassa virus (LASV) is most diverse. LASV diversity, coupled with host genetic and environmental factors, might cause differences in disease pathophysiology. Small-scale studies in Nigeria suggest that acute kidney injury is an important clinical feature and might be a determinant of survival. We aimed to establish the demographic, clinical, and laboratory factors associated with mortality in Nigerian patients with Lassa fever, and hypothesised that LASV was the direct cause of intrinsic renal damage for a subset of the patients with Lassa fever...

CONTEXT: Haematuria is a common urological presentation associated with patient anxiety and clinically relevant underlying pathology. However, the prevalence and pathophysiology of haematuria following sporting exercise is less well documented. OBJECTIVES: This review paper seeks to clarify the prevalence of microscopic and macroscopic haematuria in association with sporting exercise reported in the literature, and the pathophysiology behind it. We review the relation of haematuria to injury to the urinary tract in sport, as well as the incidence of underlying disease, urological and incidental, following investigation for exercise-induced haematuria...

Acute endocapillary glomerulonephritis, as its name suggests, is a one-time process, which usually resolves within weeks. However, in a small percentage of patients, the disease becomes chronic. In these cases, a deregulation in the alternative complement pathway, which can be caused by mutations or autoantibodies, has been proposed as a pathophysiological mechanism. As a result, the alternative complement pathway remains active after resolution of infection. We report a patient with two episodes of acute renal failure, both times diagnosed by renal biopsy of acute endocapillary glomerulonephritis, with slow recovery after two episodes of low-serum complement C3, haematuria and proteinuria...

BACKGROUND & AIMS: Haemorrhagic radiation cystitis (HRC) is a late complication of pelvic radiotherapy. Severe cases are difficult to treat due to persistent or recurrent bleeding, despite urological and hyperbaric oxygen therapy (HBOT). However, wound healing requires a good nutritional status. In this respect, we aimed at analysing the nutritional status of patients with HRC prior to the onset of HBOT and at highlighting predictive nutritional factors of outcome. METHODS: Data were retrospectively collected from a cohort of 179 patients with HRC (between 2011 and 2015)...

A 51-year-old male presented 25 years ago with excessive sweating and haematuria. Blood pressure was labile. CT abdomen showed a large right-sided adrenal mass. Two 24-h urine collections showed elevated urinary catecholamines. Right adrenal resection was performed; a phaeochromocytoma (PC) was confirmed histologically. Two decades later, the patient represented with excessive sweating and measured variable blood pressure readings. Measurement of plasma metanephrines (PMets) showed elevated normetanephrine (NMN) [50,250 (R...

Ureteral stent placement is a common procedure in urologic practice. Forgotten, encrusted D/J stents represent a difficult problem for urologists. The major complications are infection, impaired renal function, migration, encrustation, stone formation and multiple fragmentation of stent. A consensus on the best therapeutic approach is still lacking. Here we present our experience with endoscopic management of this challenging problem and discuss the multimodal endourologic approaches for treating forgotten, encrusted ureteral stents...

BACKGROUND: The prognostic effect of gender on immunoglobulin A nephropathy (IgAN) is not clear. We explored gender-related differences in clinicopathological features and renal outcomes in IgAN. METHODS: This was a single-centre retrospective study. Patients were divided into two groups according to gender. The clinicopathological features at biopsy and renal outcomes during the follow-up were collected and analysed. Renal outcomes were defined as the doubling of baseline serum creatinine and end-stage renal disease (ESRD) (estimated glomerular filtration rate < 15 mL/min/1...

Hyperlipidemia accompanies chronic renal disease either as a consequence of the renal dysfunction or as part of generalised metabolic derangements. Under both situations, the lipid profile is characterised by accumulation of triglyceride-rich lipoproteins (TGRLs). This lipid profile is increasingly recognised as a risk factor for cardiovascular complications. Whether it may pose a risk for renal injury as well remains unclear. A hyper-TGRL state was generated in C57BL/6 mice using the poloxamer-407 (P-407) and immune complex-mediated renal injury was triggered using the accelerated nephrotoxic nephritis (ANTN) model...

BACKGROUND: The association of increased cancer risk with glomerulonephritis (GN) is well known, but controversy exists concerning which types of GN are involved, and the size of the association. A national registry survey was performed to assess the size of this association, and the temporal relationship of cancer diagnosis to GN diagnosis. METHODS: All patients with biopsy-proven GN between 1985 and 2015 in Denmark were extracted from The Danish Renal Biopsy Registry and the National Pathology Data Bank...

Endometriosis is the second most common benign female genital disease after uterine myoma. This review discusses the management of individual patients. This should take into account the severity of the disease and whether the patient desires to have children. Particular emphasis is laid on the anatomical intersections which, when injured, can lead to persistent damage of the anterior, middle or posterior compartment and are not infrequently the cause of urological and urogynaecological follow-up measures. Typical symptoms of endometriosis include chronic pelvic pain, subfertility, dysmenorrhoea, deep dyspareunia, cyclical bowel or bladder symptoms (e...

Lupus nephritis (LN) affects up to 50% of patients with Systemic Lupus Erythematosus (SLE) and is associated with a worse prognosis. LN usually develops within the first 5 years of the onset of the disease. We report three patients with very delayed LN (DLN) diagnosed after 15 or more years after SLE diagnosis. The three patients were non-Caucasian women with adolescent or adult-onset SLE. Each had antinuclear, anti-dsDNA and anti-Ro antibodies. Hydroxychloroquine was prescribed for each. Their disease courses were characterised by sporadic non-renal flares controlled by steroids and, in two cases, by one cycle of rituximab...
