Obstructive uropathy is a common cause of renal impairment. Recently, there has been a burgeoning interest in exploring natural products as potential alternative remedies for many conditions due to their low toxicity, affordability and wide availability. We investigated the effect of nerolidol in a rat model of bilateral ureteral obstruction (BUO) injury.
View Article and Find Full Text PDFResearch has demonstrated that hypertension can lead to an exaggeration in the renal functional and histological changes caused by ureteral obstruction. These changes were particularly observed shortly after the release of a relatively brief period of unilateral ureteral obstruction (UUO). However, the long-term impact of hypertension on the recovery of renal functions has not been investigated beyond the immediate period after UUO reversal.
View Article and Find Full Text PDFBoth ureteral obstruction (UO) and hypertension are common conditions that affect kidney functions. Hypertension and chronic kidney disease are closely associated with an overlapping and intermingled cause-and-effect relationship. The effect of hypertension on the renal dysfunction following reversible UO has not been studied previously.

Recently, there has been increasing interest in using natural phytochemical compounds as alternative remedies in several diseases. Nerolidol is a natural product extracted from plants with floral odors and has been proven to be effective for the treatment of some conditions.

The response of the kidney and its recovery following unilateral ureteral obstruction (UUO) depend on several factors including the duration of obstruction, the species involved and the age of the individual. In neonates, there is compelling evidence to indicate that even short periods of reversible UUO might lead to long-term renal impairment. In adults, the glomerular filtration rate returns to baseline values soon after the release of short periods of UUO.

Background: Urinary incontinence (UI) in women is a common problem worldwide. It has a major impact on the physical and social activities and interpersonal relationships. The societies in the Gulf countries are conservative and favours large families, high parity and short inter-pregnancy intervals.

Neprilysin is the key enzyme responsible for the degradation of NPs. The effects of neprilysin inhibition or the combination of neprilysin inhibition and RAS inhibition on renal IRI-induced renal dysfunction have not been investigated yet.

Gas-containing renal stones are rare. Herein, we present a case of gas-containing renal matrix stone that was associated with emphysematous pyelitis and reflect on its management.

Background: Postoperative urinary leak is a well-documented complication following partial nephrectomy. It usually presents as persistent discharge from the retroperitoneal drain, nephrocutaneous fistula, urinary collection, systemic manifestations, or abdominal symptoms. Herein, we report for the first time on a case of urinary leak postlaparoscopic partial nephrectomy which did not heal and led to the formation of ureterocalyceal fistula.

Following the release of short periods of unilateral ureteral obstruction (UUO), glomerular filtration rate (GFR) recovers by time. However, research in experimental animal models has demonstrated the presence of an ongoing element of renal interstitial fibrosis a few weeks following UUO reversal. Interstitial fibrosis can cause deterioration in GFR, and it is not known whether it leads to an ongoing slow deterioration in other renal functions despite the apparent initial recovery postreversal.

Large injuries may cause excessive bleeding and fluid extravasation and require adequate drainage using several modalities such placement of JJ stents. Herein, we report on two cases in which the upper coil of the JJ stent got buried in the fibrous tissues which formed due to an injury of the collecting system during PNL.

It has been shown to be safer than percutaneous nephrolithotomy. The latter can sometimes be complicated by the formation of intrarenal arteriovenous malformation (AVM).

Introduction: Renal ischemia-reperfusion injury (IRI) causes renal functional alterations which may lead to permanent renal impairment. β-caryophyllene (BCP), a natural bicyclic sesquiterpene, is an important constituent of many edible plants including spices. It is an FDA-approved food additive which possesses potent anti-inflammatory and antioxidant activities and has been shown to protect against chemotherapeutics-induced organ toxicities and against ischemic injuries to heart, liver and brain.

Diabetes mellitus (DM) affects glomerular function; thus, the ability of diabetic kidneys to recover from UO may be impaired. This study investigated the effects of long-term DM on the recovery of glomerular and tubular function, as well as permeability of the glomerular filtration barrier (GFB), after unilateral UO (UUO) reversal.

Clinical Presentation And Intervention: During TURP, a loud explosion was heard, and a jolt was felt in the abdomen. A bladder tear was seen endoscopically.
Renal ischemia-reperfusion injury (IRI) induces the production of aldehydes which are detoxified by aldehyde dehydrogenases (ALDHs). Alda-1 is a selective ALDH2 agonist and its protective effect was demonstrated in several conditions. The effect of Alda-1 on the kidney or on renal IRI was not investigated.

Introduction: The aim of this study was to investigate the effect of thymoquinone, an antioxidant phytochemical compound found in the plant Nigella sativa, on the alterations in renal functional parameters following warm renal ischemia-reperfusion injury (IRI) in the rat.
Methods: Wistar rats underwent left renal ischemia for 35 minutes. Group-TQ (n=15) received thymoquinone 10 mg/kg/day (dissolved in a vehicle (corn oil) orally by gavage starting 4 days prior to IRI and continued 6 days thereafter when the hemodynamic and tubular renal functions of the right and left kidneys were measured using clearance techniques.

Purpose: To investigate the effect of blocking renin-angiotensin system by direct renin inhibition using aliskiren on the renal dysfunction following reversible unilateral ureteral obstruction (UO).
Methods: Wistar rats underwent reversible left UO for 72 hours. Group-Alsk (n=12) received aliskiren (30 mg/kg/day) dissolved in water starting one day before creating UO and continued until the terminal experiment five days post reversal when renal functions were measured using clearance techniques.
Background: Similar to other Gulf countries, the society in United Arab Emirates is pro-natal with high parity and high prevalence of macrosomic babies. Therefore, it is possible to have a high prevalence of pelvic organ prolapse (POP). Thus, the aim of this study was to determine the prevalence of POP symptoms in one of the UAE cities.
