PURPOSE: Management of hydrocolpos in cloaca patients is of clinical importance. We report a nonoperative method for the management of hydrocolpos in the form of initial catheter decompression, followed by an endoscopy with catheters placement into both the bladder and vagina, and leaving these catheters for 9 and 14days respectively. METHODS: The medical records of six cloaca patients with hydrocolpos in the last 12years were reviewed. The outcomes measured were the renal function, bladder emptying, the presence/resolution of hydronephrosis, and the recurrence of hydrocolpos...

Although current staging workups could differentiate most patients with operable from inoperable advanced gastric cancers, there are still some patients with low-volume peritoneal carcinomatosis, defined as only metastasis with multiple subcentimeter lesions in peritoneum, receiving unnecessary open-close procedures. The computed tomography (CT) of the patients with unresectable advanced gastric cancer harboring low-volume peritoneal carcinomatosis was retrospectively identified and then thoroughly reviewed by two independent radiologists unaware of the peritoneal carcinomatosis status...

Osr1 is a transcriptional repressor that plays critical roles in maintaining the mesenchymal stem cell population within the developing kidney. Here, we report that newborn pups with a heterozygous null mutation in Osr1 exhibit a 21% incidence of vesico-ureteric reflux and have hydronephrosis and urinary tract duplications. Newborn pups have a short intravesical ureter resulting in a less competent uretero-vesical junction which arises from a delay in urinary tract development. We describe a new domain of Osr1 expression in the ureteral mesenchyme and within the developing bladder in the mouse...

Persistent cloaca is a rare presentation wherein the urethra, vagina, and rectum converge into a common channel with a single perineal opening. Fetal hydrometrocolpos can result if fluid accumulates behind an obstruction of this common channel. A 29-year-old woman (G4P1021) was referred at 36 2/7 weeks of gestation for evaluation of a fetal abdominal cystic mass. Detailed ultrasonography and magnetic resonance imaging showed two symmetric cystic masses, bilateral hydronephrosis, and oligohydramnios. Elective cesarean delivery was performed at 37 0/7 weeks; the baby weighed 4043 g with Apgar scores of 5 and 6 at 1 and 5 min...

The horseshoe kidney is a frequent urological birth defect. The most frequent complications are urinary tract infections, stones and hydronephrosis. The occurrence of glomerular disease in horseshoe kidney is rare. Therefore, we report the first case of minimal change disease occurring in a patient with horseshoe kidney in literature. A 22-year-old Caucasian man without personal or family medical history admitted to the pneumology department for a pulmonary artery embolism. In presence of a generalized oedema, a biological assessment was performed yielding intense nephrotic syndrome with urine protein excretion 22g/day...

REVIEW
Christopher S Cooper
The human body is an unfathomably intricate structure consisting of many connected and intertwined systems. This makes it impossible for therapeutic interventions to selectively target only one physiologic system without some impact or side effects on all the other systems. The resiliency of the human body modifies and disguises side effects, some of which may be undetectable for years and not apparent without scientific investigation. Pediatric urologists employ relatively few medications for the common conditions they treat and in general these consist of antibiotics, anticholinergics, and anesthetics...

BACKGROUND: Ureterocalicostomy is indicated mainly in cases with failed pyeloplasty or with a completely intrarenal pelvis. While there have been several case series reported in adults, laparoscopic ureterocalicostomy in pediatric cases has rarely been reported. We report a case of pure laparoscopic ureterocalicostomy for ureteropelvic junction obstruction in an Asian female child. CASE PRESENTATION: A 10-year-old female patient was referred to our hospital due to right high-grade hydronephrosis and a right renal stone, which was detected due to hematuria...

CASE SUMMARY: An 11-year-old female spayed domestic shorthair cat was presented with haematuria of 2 months' duration followed by pollakiuria and stranguria. A firm, non-painful mass in the urinary bladder was palpated. Abdominal radiographs and ultrasound were suggestive of a urinary neoplasia. During explorative laparotomy, a partial cystectomy and surgical debulking were performed. Histopathology and immunostaining were consistent with a fibrosarcoma. The cat was discharged 10 days after surgery with a residual mass of about 1...
