A 78-year-old man visited our department for macroscopic hematuria in June, 1989. On the basis of the diagnosis of tumor of the bladder and right afunctional kidney, total right nephro-uretero-cystectomy and skin grafting of the left ureter were performed on August 2. The patient continued to have fever of unknown origin postoperatively. Repeat laparotomy, which was performed for rectal fistula on August 25, revealed that the abdominal wall, colon, small intestine and mesenterium adhered to one another, producing a mass and that two sites in the rectum were perforated. A part of the small intestine was excised, the perforated sites were sutured, and an artificial anus was created at the transverse colon. Since the patient had intermittent fever and continued to complain of abdominal pain after creation of the artificial anus, nosotropic therapy was continued. However, the patient died from cardiac insufficiency on October 10. Erosion and ulcer were histologically observed over a wide range in the excised small intestine. In addition there was a defect in one area of the small intestine, penetrating the tunca muscularis propria, in which many cytomegalovirus (CMV) inclusion bodies were observed. CMV inclusion bodies were also detected in the bladder with re-examination of specimens from the excised bladder. From these findings, it appears that endogenetic CMV may have been reactivated in the present case.

Nephrogenic metaplasia of the bladder is rare; less than one hundred cases have been reported. Four personal cases and 16 cases reported in the literature concerning renal transplant patients demonstrate that the frequency of this disease is much higher in this group than in the general population. The symptoms and signs, age of onset, macroscopic and microscopic appearance of the lesions correspond to the description in non-transplant patients, apart from the preferential site adjacent to the reimplanted ureter and the presence, in two cases, of cells with virus-like inclusions, one of which corresponded to CMV infection. The traumatic factor in these patients is not sufficient on its own to explain the relative frequency of this lesion in renal transplant patients. The role of immunosuppression, resulting in a reduction of "immunological surveillance", is possible; this metaplasia usually has a benign course, but this high risk population must be carefully monitored for the development of this lesion.

We report a case of invasive cytomegalovirus (CMV) infection in the native ureter of a patient 7 years after liver-kidney transplantation. Previous reports of CMV ureteritis in transplant patients have involved only the allograft ureter, usually within 3 months of transplantation. The common characteristics of these patients, the possible risk factors, and the diagnostic findings of CMV ureteritis are discussed. Combined surgical and medical intervention are required for successful treatment.

Nephrogenic adenoma (NA), a rare benign lesion of the urinary tract, is widely accepted to be a metaplastic reaction due to urothelial injury. It mainly occurs in the urinary bladder and rarely in the ureter. Renal transplant recipients are prone to the development of NA. However in those patients, NA was diagnosed exclusively in the bladder. Herein, we present the--to our knowledge--first case of NA involving a transplanted ureter. A 42-year-old female kidney transplant recipient suffered hematuria, oliguria, and acute renal failure and presented with ureteral obstruction and hydronephrosis of the renal transplant. To our surprise, evidence of cytomegalovirus (CMV) infection of the NA was demonstrated using special immunohistochemical staining. The findings in this case raise the possibility that CMV infection, as an irritant of the ureteral epithelium, may be an etiological factor of NA.

Gene transfer into kidney holds great potential as a novel therapeutic approach. We have studied the transduction of kidney in vivo after delivery of lentiviral vectors by various routes of administration. A lentiviral vector expressing the bacterial lacZ gene from the cytomegalovirus early promoter was used. The lentiviral vector was delivered into the kidneys of BALB/c mice by retrograde infusion into the ureter, by injection into the renal vein or artery, or by direct injection into the renal parenchyma. Expression of the reporter gene was achieved independently of the route of administration, although it appeared more efficient after parenchymal or ureteral administration. After parenchymal or ureteral infusion, expression of the transgene was localized to the outer medulla and corticomedullary junction. In the case of parenchymal injection, expression of the reporter gene extended to the cortex. Detection of the transgene in the renal proximal tubules was confirmed by in situ polymerase chain reaction after parenchymal or ureteral infusion. On delivery of the lentiviral vector through the renal artery or vein, expression of the reporter gene was markedly lower than was observed with parenchymal or ureteral infusion and was limited to the inner medullary collecting ducts. No apparent histological abnormality was observed after virus administration and transgene expression was stable for at least 3 months. These results provide the first evidence that lentiviral vectors can stably transduce renal cells in vivo and may be effective vehicles for gene delivery to the kidney.

A middle-aged woman presented with painless hematuria and passage of large clots. Two weeks earlier, she had pyrexia with upper respiratory tract symptoms. Imaging studies revealed no lesions of the urinary tract. Cystoscopy showed clots and oozing of blood from the left ureteric orifice. Urine cytology and mucosal biopsies were normal. Left nephroureterectomy was done as an emergency procedure; the hematuria stopped following the procedure. Histopathology revealed cytomegalovirus inclusion bodies in the mucosa of the excised ureter. This unusual presentation of hematuria has not been reported previously.

There are many causes of frequent urination. Whenever water or fluids are consumed, the patient has to urinate within 10 or 20 min. Often urinary bladder examinations & blood tests show no significant abnormalities, & treatment by anti-bacterial or anti-viral agents does not improve the symptoms significantly. In intractable frequent urination with difficulty holding urine, as well as other intractable medical problems such as frequent coughing, white pus in gingiva, infection of the apex of a root canalled tooth, slow-healing wounds, & ALS, the authors often found coexisting mixed infections of Candida albicans (C.A.), Helicobacter pylori (H.P.), & Cytomegalovirus (CMV) with or without additional bacterial (Chlamydia trachomatis, etc.) or viral infections & increased Asbestos, with or without Hg deposits. We often found various degrees of mixed infections with C.A., H.P., & CMV in the external sphincters of the urethra & in the Trigone of the urinary bladder which consists of (1) a horizontal, band-like area between the 2 ureter openings & (2) the funnel shaped part of the Trigone at the lower half of the urinary bladder. In the coexistence of significant amounts of C.A., H.P. & CMV, the infection cannot be reduced by otherwise effective medicines for H.P. & CMV. However, one optimal dose of Diflucan, or Caprylic acid taken orally or externally applied, rapidly reduced the symptoms significantly. We found the best treatment is to give a combination of an optimal dose of Caprylic acid orally in the form of "CaprilyCare" or "Caprylic Acid," with a capsule of Omega-3 Fish Oil as an anti-viral agent, Amoxicillin, Substance Z & a Cilantro tablet. We found that an optimal dose of Caprylic acid increases normal cell telomere (NCT) to a desirable 750 ng BDORT units while Diflucan increases NCT by only 25 ng BDORT units, & with Omega-3 fish oil, leads to a mutual cancellation of both drugs. Thus, Caprylic acid is superior to & less expensive than Diflucan, & has potential application for anti-cancer, anti-aging, anti-Alzheimer's disease, anti-Autism, anti-infection, & general circulatory improvement.

We report a case of minimally invasive nephrectomy of a kidney transplanted into the abdominal cavity in a child. A 15-year-old girl underwent transplantation with a cadaveric donor kidney due to congenital pyelonephritis, vesicoureteral reflux, and secondary bladder atrophy. The transplant was complicated by hyperacute rejection, cytomegalovirus infection, and anastomotic stenosis of the Bricker neobladder. After recurrent urinary tract infections, the patient was reintroduced to hemodialysis in 2010. After pneumo-peritoneum, we placed 2 10-mm trocars in the hypochondrium and left side and 2 5-mm in the left iliac fossa and right upper quadrant. The transplanted kidney was skeletonized, the artery and vein were cut to the end-to-side anastomoses to the juxta-renal aorta and cava using an automatic 35-mm, stapler, and the ureter was dissected and closed with clips. Via a Pfannestiel minilaparotomy we extracted the allograft. The patient was discharged on the third postoperative day. After 4 months of follow-up, she is alive an on dialysis. Laparoscopic nephrectomy of a kidney transplanted into the abdominal cavity is feasible and safe in centers with skilled minimally invasive techniques.

BK virus nephropathy (BKVN) is an important clinical problem in kidney transplant (KT) recipients. The sequence of disease is usually viruria, viremia and then nephropathy. Diagnosis of BK virus (BKV) infection includes checking BKV DNA in the urine, in the plasma and histology on renal biopsy. This last method is used to diagnose BKVN. We describe a KT patient with BKVN without detectable BK viremia. A 62-year-old female with hypertensive nephropathy underwent renal transplant from a living relative donor in December 2011. Fourteen months after transplantation, her serum creatinine(SCr) rose up from 1.2 to 1.6 mg/dl with biopsy-proven acute antibody-mediated and cellular rejection. After pulse methylprednisolone, plasmapheresis and intravenous immunoglobulin, her SCr decreased to baseline but she subsequently developed cytomegalovirus infection with pancytopenia and transaminitis. The SCr rose to 1.9 mg/dl despite ganciclovir treatment. Renal ultrasound and antegrade pyelogram showed partial obstruction of the proximal ureter with moderate hydronephrosis. A quantitative polymerase chain reaction (PCR) assay for BKV DNA was negative (less than 10 copies/ml). A renal biopsy was performed and the pathology revealed viral cytopathic changes in the tubular epithelium with interstitial inflammation. The renal biopsy also showed BKV nucleic acid sequences by in-situ hybridization confirming BKVN. Immunosuppression regimen was changed to cyclosporine, low-dose prednisolone and leflunomide. A temporary percutaneous nephrostomy was performed. Her renal function improved within one week. The diagnosis of BKVN should be considered in a KT recipient with a rising SCr with or without BK viremia and should be made by renal biopsy.
