Recurrent thromboses and major vessel compressions in autosomal dominant polycystic kidney disease.

A 41-year-old man with autosomal dominant polycystic kidney disease (ADPKD), who had multiple previous unprovoked thrombotic events and without a known coagulopathic disorder, presented with symptomatic extensive thrombus distal to the compression site of the left common iliac vein by a dominant cyst in the left inferior renal pole. This was managed with inferior vena cava filter insertion, left nephrectomy and warfarinization. Later, there was inferior vena cava compression by the right polycystic kidney, leading to elective right nephrectomy. Post-renal transplantation, he had further episodes of partial dialysis access stenosis and extensive thromboses in the left deep and right superficial venous systems of the lower limbs despite absence of extrinsic compression. This represents the first report of recurrent mass effect and thromboembolic events in ADPKD, both before and after nephrectomy and anticoagulation. The potential increased thromboembolic risks among patients with ADPKD warrant further investigation.

A Single Center Experience With Adult Dual Kidney Transplant.

OBJECTIVES: Our renal transplant center in South Australian has been at the forefront of dual kidney transplants in Australia. In this study, we reviewed the 17 adult dual kidney transplants performed at our center between 1998 and 2014. MATERIALS AND METHODS: We retrospectively reviewed the 17 adult dual kidney transplants performed at our center since 1998 and report data pertaining to donor demographics, preimplant function, and histology of donor kidneys, as well as postoperative outcomes of transplant recipients. RESULTS: The mean age of donors was 68.5 ± 7.27 years, with 47% presenting with comorbid disease adversely affecting renal function (diabetes or hypertension). Histologic sampling of donor kidneys showed high rates of glomerular obsolescence, scarring, and vascular sclerosis. The mean age of recipients was 57.18 ± 10.93 years, with 10 patients receiving kidneys that were implanted bilaterally in each iliac fossa and 7 patients having both kidneys implanted into 1 iliac fossa. Early surgical complications (within the first 2 wk) were found in 6 patients (4 bilateral, 2 unilateral). In patients with bilaterally placed grafts, 2 developed a urinary leak, 1 lost both grafts secondary to renal vein thrombosis, and 1 lost a single graft due to renal vein thrombosis. In patients with unilaterally placed grafts, 1 had wound infection and 1 had double graft loss related to renal vein thrombosis. CONCLUSIONS: Adult dual kidney transplants offer an alternative use of kidneys from marginal donors.

Procalcitonin Strip Test as an Independent Predictor in Acute Pancreatitis.

Plasma procalcitonin (PCT) is a highly specific marker for the diagnosis of bacterial infection and sepsis. Studies have demonstrated its role in the setting of sepsis and acute pancreatitis. This study aims to analyze and compare the prognostic efficacy of plasma procalcitonin strip test in acute pancreatitis. A prospective study was conducted in the department of general surgery from June 2012 to June 2013. Plasma procalcitonin was estimated by the semiquantitative strip test. The study included a total of 50 patients diagnosed to have acute pancreatitis. Data was collected and statistically analyzed using SPSS version 17. Thirty-nine out of the 50 patients (78 %) were males with a mean age of 46.8 years (range, 25-78 years) and 25 patients (50 %) had ethanol-induced pancreatitis, while 13 patients (26 %) had gall stone pancreatitis. Plasma PCT values were found to correlate better than CRP levels and total leukocyte count with the total duration of hospitalization, ITU, and ICU stay, as well as with the progression to severe acute pancreatitis. A cut off for plasma PCT of >2 ng/mL was found to be 100 % sensitive and 100 % specific and a cut off for CRP of >19 mg/dL was 70 % sensitive and 65 % specific for predicting the progression to severe acute pancreatitis. Plasma PCT also correlated well with antibiotic requirement. A cut off value of >0.5 ng/mL for plasma PCT was 100 % sensitive and 80 % specific and a cut off value of >18 mg/dL for CRP was 86 % sensitive and 63 % specific for predicting antibiotic requirement. Plasma procalcitonin is an early and reliable prognostic indicator in acute pancreatitis. The procalcitonin strip test is a rapid test which is useful in analyzing prognosis in patients with acute pancreatitis.

Perspectives of laparoscopic donors toward a new procedure: transvaginal donor nephrectomy.

BACKGROUND: Interest in natural orifice transluminal endoscopic surgery (NOTES) is increasing. Transvaginal NOTES (TVNOTES) donor nephrectomy with subsequent removal of the kidney via the vagina is technically possible. This approach may minimize the surgical insult to the donor and allow improved cosmesis. The acceptability to patients of such a technique is, however, unknown. The aim of this article is to explore the attitudes of women who have previously undergone laparoscopic donor nephrectomy (LDN). METHODS: A 15-point questionnaire was designed by a multidisciplinary group of surgeons interested in minimally invasive surgery to obtain the views of women who had previously undergone LDN at the Queen Elizabeth Hospital, Adelaide. It was sent to 150 female donors, and their views with regard to the acceptability of a TV approach to the peritoneal cavity for donor nephrectomy were recorded. RESULTS: Forty-nine patients returned the completed questionnaire. The majority (90%) of these women did not have adverse feelings toward scars. Thirty-seven percent of women would consider a TVNOTES donor nephrectomy; however, this was increased to 51% if they could be reassured that TVNOTES was as safe as LDN. Concerns regarding a negative impact on sexual function after this procedure were raised by 33% of patients. The majority (88%) did not cite surgeon gender as an important factor when deciding for or against this procedure. CONCLUSIONS: This study demonstrates that less postoperative pain, better cosmesis, and safety are factors that may influence a patient's decision to choose TVNOTES donor nephrectomy. The majority, however, would still prefer LDN.
