Negative-pressure pulmonary edema (NPPE) or postobstructive pulmonary edema is a well-described cause of acute respiratory failure that occurs after intense inspiratory effort against an obstructed airway, usually from upper airway infection, tumor, or laryngospasm. Patients with NPPE generate very negative airway pressures, which augment transvascular fluid filtration and precipitate interstitial and alveolar edema. Pulmonary edema fluid collected from most patients with NPPE has a low protein concentration, suggesting hydrostatic forces as the primary mechanism for the pathogenesis of NPPE...

BACKGROUND: Vesicoureteral reflux is thought to predispose to urinary tract infection and renal scarring, and ureteral reimplantation in childhood remains the gold standard for its treatment. It has been reported that the risk of postrenal failure during pregnancy is increased among women with Politano-Leadbetter ureteral reimplantation. In previous case reports on patients with progressive hydronephrosis and renal failure during pregnancy after ureteral reimplantation, percutaneous nephrostomy was always required, so there has been no information about the clinical management of such patients by ureteral stenting...

Urinary retention is an emergency that rarely occurs during pregnancy. Previous case reports have suggested multiple risk factors that can cause the gravid uterus to become impacted in the pelvis leading to lower bladder or urethral compression with subsequent urinary retention. However, no cases of urinary obstruction in a pregnancy that was complicated with severe electrolyte imbalance have been reported. To our knowledge, we report the first case of a 31-year-old woman presenting at 8 weeks' gestation with acute urinary retention caused by a retroflexed, retroverted uterus with a 6-cm posterior uterine fibroid leading to syndrome of inappropriate antidiuretic hormone secretion and severe hyponatremia requiring intensive care unit admission...

UNLABELLED: Diuretic nephrogram is important diagnostic tool in the postnatal follow-up of asymptomatic antenatally detected hydronephrosis (HN). In the last decades, two quantitative indices of renal excretion, output efficiency and the residual kidney counts normalized to the 1-2min counts (normalized residual activity, NORA) have been proposed, that enhance the accuracy of technique to detect kidneys with obstruction. Unfortunately, in many nuclear medicine departments in developing countries the obsolete computer systems do not give the opportunity of sophisticated analysis of nephrogram...

BACKGROUND: Suprapubic catheter (SPC) insertion is a common urological procedure. Though considered a simple and safe procedure, complications are bound to occur if proper precautions are not taken during the procedure. The reported complications include gross hematuria, post-obstruction diuresis, insertion site skin-related complications, and intra-abdominal visceral injuries. Iatrogenic bowel injuries have been reported to occur as a complication in around 2.5% of cases. CASE REPORT: We report a very rare case of a bowel injury due to improper insertion of a SPC leading to fecal matter tracking along the muscle planes to reach the fracture site of the femur shaft and formation of an external fecal fistula along the lateral aspect of thigh, which according to us is the first reported case in the literature...

Herein, we present a successfully treated case with acute renal failure due to ureteral obstruction caused by total uterine prolapsed. A 55-year-old female patient presented to our hospital with the complaints of protrusion of the uterus for the last 3 months, pollakiuria, nocturia, decreased urine volume, and swelling of her body for the last week, and as well as impaired general status with shortness of breath for the last several days. Her physical examination revealed a blood pressure of 140/90 mmHg, pulse rate of 80 beats/min, body temperature of 37...

We carried out a prospective study of consecutive patients who presented with chronic urinary retention over a period of 2 years in order to determine the safety and effectiveness of rapid and complete decompression of chronic urinary retention. A total of 22 patients met the inclusion criteria. Although slow decompression is thought to reduce complications, it harbours the disadvantages of impracticability, time and labour demands and an increased risk of infection. Post-obstructive diuresis, haematuria and hypotension are relatively frequent in rapid and complete decompression of chronic urinary retention...

UNLABELLED: Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? The pathophysiology of post-renal acute kidney injury (PR-AKI), i.e. caused by urinary tract obstruction, has been extensively studied in animal models but clinical studies on this subject are outdated, and/or have focused on the mechanisms of 'post-obstructive diuresis' (POD), a potentially life-threatening polyuria that can develop after the release of obstruction...

BACKGROUND/AIMS: Unilateral ureteral obstruction (UUO) results in renal injury. Studies report increased injury indices in male rats following UUO. Our study examined whether this gender-based renal response to UUO was reflected in sustained differences following relief of obstruction. METHODS: Adult male/female rats (200-400 g) were subjected to either sham surgery (S/RN) or UUO (UUO/RN). At 24 h, obstruction was relieved and all animals underwent contralateral nephrectomy...

Facticious accumulation of the radiopharmaceutical in the urinary draining system as shown by routine renal tests, like technetium- 99m-diethylenetriamine pentacetic acid, technetium-99m-mercaptylacetyltriglycine or technetium-99m-glucoheptonate renograms can be re-evaluated by administering a diuretic, like furosemide (FS) and obtaining post FS dynamic and static images. Urinary tract obstruction can thus be identified. Partial urinary tract obstruction, the effectiveness of stenting, the effectiveness of obstruction correcting surgery and retroperitoneal lymph nodes, may be diagnosed after FS induced diuresis...

OBJECTIVES: A non-invasive method to measure the bladder pressure in males using a condom catheter has been developed. The measurement technique, its validation and limitations, a diagnostic nomogram to non-invasively diagnose bladder outlet obstruction (BOO), and results of large-scale application are discussed. METHODS: Modified incontinence condoms are attached to the penis. During voiding the flow of urine is mechanically interrupted. The subsequent maximum pressure in the condom reflects the isovolumetric bladder pressure...

PURPOSE: There is little consensus regarding long-term followup of renal function in patients who undergo urinary diversion. We established the usefulness of combined serial isotopic glomerular filtration rate measurement and diuresis renography in the early identification of patients at risk for deterioration of renal function following ileal conduit diversion. MATERIALS AND METHODS: A total of 340 patients with ileal conduit diversion who were followed between 1990 and 2000 were identified...

A 70-year-old man with clinically localised prostate carcinoma underwent extraperitoneal endoscopic radical prostatectomy. His medical history revealed hypertension, renal colic, hypogonadotropic hypogonadism and recurrent deep venous thrombosis in the legs. The operation was uneventful with 500 ml blood loss and no periods ofhypotension. The patient developed oliguria within 12 h after surgery. A hypovolemic state was initially suggested to explain the oliguria and increasing amounts of intravenous fluids were administered...
