IgG4-related disease (IgG4-RD) is a fibroinflammatory disease of unknown etiology, which is characterized by a tendency to form tumefactive lesions, increased serum levels of IgG4, and massive infiltration of IgG4-positive plasma cells with storiform fibrosis and/or obliterative phlebitis. Patients with IgG4-RD have frequently multiorgan involvements such as the pancreas, biliary tree, salivary glands, periorbital tissues, kidneys, lungs, lymph nodes, and retroperitoneum. IgG4-RD mainly affects middle-aged to elderly men except for involvement in lachrymal and salivary glands, so-called Mikulicz's disease...

OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

OBJECTIVE: Endometriosis is an estrogendependent disease. The incidence of urinary tract endometriosis (UE) increased during the last few years and, nowadays, it ranges from 0.3 to 12% of all women affected by the disease. The ureter is the second most common site affected. The ureteral endometriosis is classified in extrinsic and intrinsic. The aim of this study is to individuate the best treatments for each subset of ureteral endometriosis. MATERIALS AND METHODS: 32 patients diagnosed with surgically treated UE were retrospectively reviewed...

A 50-year-old man with intractable anal pain attributed to proctalgia fugax underwent insertion of a sacral nerve stimulator via the right S3 vertebral foramen for pain control with good symptomatic relief. Thirteen months later, he presented with signs of sepsis. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a large presacral abscess. MRI demonstrated increased enhancement along the pathway of the stimulator electrode, indicating that the abscess was caused by infection introduced at the time of sacral nerve stimulator placement...

A 70-year-old man, complaining of percutaneous fistula with jelly-like yellow mucus in right kidney for a month, was admitted to our department. From computer tomography, stones and severe hydronephrosis but no suspicious mass was found in right kidney. Nephrectomy of right kidney was performed and pathological examination revealed a villous adenoma in renal pelvis with moderate to severe atypical hyperplasia of glandular epithelium. Primary villous adenoma in renal pelvis is rare and believed to be related to chronic irritation of stone and inflammation...

Ipsilateral inguinal herniation of the transplanted ureter has been reported as a rare cause of obstructive uropathy in renal transplant recipients. A 73-year-old man presented with acute renal failure 29 years after receiving a deceased donor renal transplant. Radiological investigations demonstrated marked hydronephrosis of the left iliac fossa transplant kidney and herniation of the distal transplant ureter and bladder into the right inguinal canal. The patient underwent placement of a nephrostomy and antegrade stent followed by definitive hernia repair with return of graft function to baseline level...

Primary epithelial tumour of the renal pelvis is a rare entity. So far, very few cases are reported in literature. Of these, mucin secreting adenocarcinomas are distinctly rare. However, mucinous cystadenocarcinoma, that too arising in a horse shoe kidney is extremely rare to be reported. Mucinous cystadenomas and carcinomas arising from the renal pelvis are regarded to be secondary to a metaplastic change in the urothelium. Here, we present a case of a 51-year-old male, who complained of abdominal pain, palpable abdominal mass, haematuria along with passage of mucoid material in the urine, with a very poorly functioning kidney...

Retrocaval ureter or circumcaval ureter is a rare congenital abnormality arising from dysgenesis of the inferior vena cava (IVC) that results in the right ureter coursing behind and medial to the IVC. The ideal nomenclature for the anomaly is preureteral vena cava, keeping in mind the aberrant embryology. It can result in hydronephrosis and is a rare cause of long-standing cyclical pain abdomen. Ultrasound, intravenous urography, nuclear scintigraphy, computed tomography urography (CTU) and magnetic resonance urography (MRU) have been used in the diagnosis of this abnormality but CTU, with its ability to depict the abnormality in three dimensions gives the most "wholesome" solution to its diagnosis...

The clinical picture of IgG4-related disease (IgG4-RD) is diverse because various organs can be affected. We describe the case of a 56-year-old man with acute renal failure and tuberoinfundibular hypophysitis due to IgG4-RD. Steroid therapy lowered the serum IgG4 level and ameliorated renal dysfunction, bilateral hydronephrosis and retroperitoneal fibrosis. However, polyuria from post-obstructive diuresis and unmasked central diabetes insipidus ensued. The patient's polyuria continued despite the administration of a therapeutic dose of glucocorticoid; the patient's pituitary swelling and anterior pituitary dysfunction were partially ameliorated...

OBJECTIVE: We present molecular cytogenetic characterization of mosaicism for a small supernumerary marker chromosome (sSMC) derived from chromosome 8. MATERIALS AND METHODS: A 35-year-old woman underwent amniocentesis at 16 weeks of gestation because of advanced maternal age. Amniocentesis revealed a karyotype of 47,XY,+mar[20]/46,XY[39]. However, array comparative genomic hybridization analysis on the subcultured amniocytes revealed no genomic imbalance. Prenatal ultrasound showed bilateral ventriculomegaly, intrauterine growth restriction, and an enlarged right atrium...

INTRODUCTION AND HYPOTHESIS: Surgical repair options for pelvic organ prolapse (POP) include native tissue, allograft, xenograft, and synthetic grafts. Solvent-dehydrated dermal allograft (SDDG) has an improved safety profile. We evaluated the long-term safety and efficacy of SDDG use for cystocele repair. METHODS: A total of 184 patients completed a minimum follow-up of 12 months. Incontinence Impact Questionnaire (IIQ), Urogenital Distress Inventory (UDI), and Visual Analogue Scale (VAS) were used pre and post operatively...

BACKGROUND/PURPOSE: To retrospectively evaluate the failure patterns of multimodality bladder-preserving therapy in patients with muscle-invasive bladder cancer. METHODS: Patients with muscle-invasive bladder cancer underwent maximal transurethral resection of bladder tumor and induction chemotherapy, followed by concurrent chemoradiotherapy (CCRT). Radiotherapy was given with 45 Gy to the pelvis, 50.4 Gy to the bladder, and 64.8 Gy to the tumor bed. Three protocols of trimodality treatment were used: Protocol A, three cycles of cisplatin and fluorouracil (CF), followed by CCRT with 6 weekly cisplatin; Protocol B, three cycles of weekly paclitaxel plus CF, followed by CCRT with 6 weekly paclitaxel and cisplatin; Protocol C, three cycles of gemcitabine and cisplatin, followed by CCRT with 6 weekly cisplatin...
