The authors report the first case series of conventional laparoscopic partial nephrectomy in Thailand Laparoscopic partial nephrectomy was successfully performed in two patients with small renal tumors. The first patient underwent transperitoneal laparoscopic partial nephrectomy for a 3.8 x 3.3 cm renal mass. Intraoperative blood loss was 100 ml with warm ischemic time of 38 minutes. Pathologic...

Metaplastic changes in the renal pelvis are infrequent and may be malignant transformations to adenocarcinoma. The current study reports a case of intestinal metaplasia in the right renal pelvis, which was associated with staghorn calculi, in a 56-year-old female. The patient underwent a percutaneous nephrolithotomy. Immunohistochemical assessment of the mucosa of the renal pelvis revealed the ...

The metastasis of chromophobe renal cell carcinoma to head and neck region, described herein, has never been reported before to our knowledge. A 56-year-old woman with a history of nephrectomy, that revealed chromophobe renal cell carcinoma six years before, presented left cervical mass. Imaging showed with left cervical lymphadenopathies and thyroid nodule. Surgery with histopathological exami...

BACKGROUND Inflammatory pseudotumor of the kidney or inflammatory myofibroblastic tumor (IMT) is composed of spindle cells admixed with variable amount of proliferating myofibroblasts, fibroblasts, extracellular collagen, lymphocytes and plasma cells. This mainly affects the urinary bladder or prostate. Renal involvement is rare. CASE PRESENTATION A 56 year-old man was diagnosed with asymptom...

Nephrectomy of a failed kidney transplant is indicated for hematuria and local pain (usually attributed to rejection), but may be done electively to facilitate cessation of immunosuppression. Transplant nephrectomy may also limit long-term cardiovascular risk (1). Despite these potential benefits, transplant nephrectomy can be complicated by morbidities surrounding surgery, and several retrospe...

BACKGROUND Laparoscopic simple nephrectomy is the standard procedure for the removal of non-functioning benign kidney. It can be performed transperitoneally or retroperitoneally. There are several studies comparing the results of transperitoneally or retroperitoneally laparoscopic nephrectomy but there are limited numbers of study comparing results of laparoscopic transperitoneal simple nephrec...

We investigate the equation (ut + (f(u))x)x = f (u)(ux)/2 where f(u) is a given smooth function. Typically f(u) = u/2 or u/3. This equation models unidirectional and weakly nonlinear waves for the variational wave equation utt − c(u)(c(u)ux)x = 0 which models some liquid crystals with a natural sinusoidal c. The equation itself is also the Euler-Lagrange equation of a variational problem. Two n...
