Principles of urinary tract reconstructive surgery.

CONCLUSIONS: With the worldwide expansion of minimally invasive surgery in the area of laparoscopy and robotics, it has been possible to reproduce many of the reconstructive techniques that have followed the evolutionary course of surgery from the open to the robot assisted technique, which has made clear that such therapeutic options exist and are reproducible with good results.

We appreciate this study which results according to the literature. It is clear that ureteral or bladder endometriosis could lead to a silent loss of renal function. ” A relatively limited number of patients who are currently not considered to be at true risk of urinary involvement have possible late diagnosis of renal failure.”1 Early diagnosis of hydronephrosis is critical to preserve renal function in these young patients. “As such we believe that patie nts with suspected or proven pelvic endometriosis should systematically undergo a sonographic kidney evaluation during routine gynecological sonographi...

To date there have been no studies that describe the ultrasonographic evaluation of kidney development in canine fetuses. The aim of this prospective and longitudinal study was to monitor fetal kidney development with ultrasound and use fetal kidney measurements as a complementary biometric index for estimation of gestational age. Ultrasonographic examinations were performed on 15 clinically healthy pregnant bitches every four days from 30th day of pregnancy, until visualization of the fetal renal pelvis was no longer possible.

ConclusionFrs2α(ST-/-) embryos have aberrant ureteric induction sites, improper ureteral insertion, shortened intravesicular lengths, and VUR. Induction site defects appear secondary to reduced Bmp4 expression, similar to Fgfr2 mutants. PMID: 29135976 [PubMed - in process]

A 65-year-old female presented with recurrent urinary tract infections. A computed tomography of the abdomen and pelvis shows a dilated and malrotated right renal pelvis consistent with a ureteropelvic junction (UPJ) obstruction as well as multiple renal arteries arising from the aorta. A computed tomography angiography (CTA) revealed five separate renal arteries originating from the aorta with a single renal artery crossing over and obstructing the right renal pelvis. On Lasix renogram, the affected kidney contributes 45% of total renal function.

“All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.” Innovations in medicine arise from challenging accepted traditions, and this quote (often attributed to Schopenhauer) may describe many innovations in th e past, present and future. The authors report clinical outcomes of an innovation, ureteral clipping for low or nonfunctioning renal moieties, after previously reporting a smaller series (reference 4 in article).

We report the case of a 59-year-old man presenting with EPS who underwent enterolysis at the age of 50, following 15 years of peritoneal dialysis (PD) and peritonitis. During the patient's first surgery, complete surgical enterolysis could not be performed due to severe intestinal adhesions with a deteriorated/calcified small bowel. Six months after the surgery, the obstructive bowel symptoms occurred several times a year. Nine years later, the patient suffered cystitis-like symptoms and fecal discharge from the urinary meatus. The patient was subsequently diagnosed with EPS recurrence with ureteroileal fistula between the...

In this study, we utilize hyperpolarized 13C MRI to evaluate metabolic markers in the kidneys longitudinally in a mouse model of partial unilateral ureteral obstruction (pUUO). Partial obstruction was surgically induced in the left ureter of nine adult mice, leaving the right ureter as a control. 1H and hyperpolarized [1‐13C]pyruvate MRI of the kidneys was performed 2 days prior to surgery (baseline) and at 3, 7 and 14 days post‐surgery. Images were evaluated for changes in renal pelvis volume, pyruvate, lactate and the lactate to pyruvate ratio. After 14 days, mice were sacrificed and immunohistological...

Conclusions Our data suggest that tamsulosin use benefits distal ureteral stones in facilitating stone passage and relieving renal colic. Subgroup analyses find that tamsulosin provides a superior expulsion rate for stones >5mm, but no effect for stones ≤5mm. Patient summary In this report, we looked at the efficacy and safety of tamsulosin for the treatment of distal ureteral stones. We find that tamsulosin significantly facilitates the passage of distal ureteral stones and relieves renal colic. Administration of tamsulosin significantly facilitates the passage of distal ureteral stones and relieves renal colic comp...
