OBJECTIVE: To investigate the best criteria for discriminating fetuses with isolated posterior urethral valves from those theoretically not eligible for fetal treatment because of complex megacystis, high chance of spontaneous resolution, and urethral atresia. METHODS: A retrospective national study was conducted in fetuses with megacystis detected before 17 weeks' gestation (early megacystis). RESULTS: In total, 142 cases with fetal megacystis were included in the study: 52 with lower urinary tract obstruction, 29 with normal micturition at birth, and 61 with miscellaneous syndromal associations, chromosomal and multiple structural abnormalities (complex megacystis)...

Shorty Johansson, Rustin Walters, Kaitlyn Mayer, Stuart Shippey
BACKGROUND: Leiomyomas can develop after hysterectomy and, when located in the bladder, can result in voiding dysfunction and incontinence. CASE: Fifty years after a hysterectomy, a 77-year-old woman presented with a 1-year history of urinary retention requiring self-catheterization and bothersome urinary incontinence. Multiple imaging modalities demonstrated a well-circumscribed 2-cm mass abutting the bladder beneath the trigone. After ureteral stent placement, we excised the nonpalpable mass using ultrasound guidance...

Dual-modal photoacoustic (PA) and ultrasound (US) contrast agents are becoming increasingly popular in recent years. Here, a flow-focusing junction based microfluidic device is used for the generation of nitrogen microbubbles (<7 μm) in two photoacoustic contrast agents: methylene blue (MB) and black ink (BI). The microbubble diameter and production rate could be precisely controlled in both MB and BI solutions. Microbubbles were collected from the outlet of the microfluidic device and optical microscope was used to study the size distributions in both solutions...

Jason P Van Batavia, Andrew J Combs
PURPOSE OF REVIEW: The symptoms of lower urinary tract dysfunction (LUTD) including urinary incontinence, frequency, and urgency are among the most common reasons children are referred to pediatric urologists. Despite this, the workup for LUTD is often time consuming and a source of frustration for patients, parents, and clinicians alike. In the current review, we summarize the important role non-invasive testing plays in the diagnosis and management of children with LUTD and to show how use of these tests can help avoid the need for more invasive testing in the majority of children...

We describe the case of a previously 77-year-old man who accessed in our Nephrology Unit for acute kidney injury (AKI) on chronic kidney disease (CKD), gastric discomfort and vague urinary symptoms with apparently preserved diuresis and suspected "ascites". Physical examination confirmed the presence of abdominal effusion, even though ultrasound abdominal examination revealed the presence of a giant diverticular urinary bladder with bilateral hydronephrosis. We discuss the diagnostic and therapeutic approach of these rare complications by briefly reviewing the technical aspects and the possible consequences...

29-year-old female presenting with an 8-year history of unexplained hypomagnesaemia, which was severe enough to warrant intermittent inpatient admission for intravenous magnesium. Urinary magnesium was inappropriately normal in the context of hypomagnesaemia indicating magnesium wasting. Ultrasound imaging demonstrated unilateral renal cysts and computed tomography of kidneys, ureters and bladder showed a bicornuate uterus. Referral to genetic services and subsequent testing revealed a de novo HNF1B deletion...

A spontaneous, non-traumatic, urinary bladder rupture is a rare condition. We describe a case of a 23-year-old male with a spontaneous bladder rupture secondary to urinary retention, due to an urethral stricture. He presented to the emergency department with voiding difficulties, severe abdominal pain and renal failure. Abdominal ultrasound revealed large amounts of ascites. After an unsuccessful attempt to place a Foley catheter a cystoscopy was performed which showed an urethral stricture. On CT-cystogram an intra-peritoneal bladder rupture was diagnosed and the patient underwent laparoscopic repair of the bladder wall...

Ultrasound scanning of bladder volume is used for prevention of postoperative urinary retention (POUR). Accurate assessment of bladder volume is needed to allow clinical decision-making regarding the need for postoperative catheterization. Two commonly used ultrasound devices, the BladderScan® BVI 9400 and the newly released Prime® (Verathon Medical®, Bothell, WA, USA), with or without the 'pre-scan' option, have not been validated in clinical practice. The aim of this study was to assess the performance of these devices in daily clinical practice...

Persistent urogenital sinus (PUGS) is a congenital pathological condition characterized by an abnormal communication between the urethra and vagina, which has an estimated incidence of 0.6/10,000 female births. It could be the only known malformation or part of a syndrome. PUGS is commonly shown by a pelvic mass, related to a distended bladder, hydrometrocolpos which is due to an obstruction leading to the dilation of the vagina and uterus (i.e., imperforate hymen, transverse vaginal septum or atresia, and PUGS) or both...

INTRODUCTION: Congenital Zika Syndrome (CZS) has been associated with microcephaly and other central nervous system abnormalities including areas that have been implicated in the control of the lower urinary tract. As such, this descriptive case series has aimed to investigate whether CZS is linked with neurogenic bladder. Identifying such an association is paramount in the effort to recognize CZS complications that have putative treatment options that could mitigate the impact of CZS in infected children...

AIMS: Neurogenic bladders (NGB) with detrusor leak point pressures >40 cm H2 O (dLPP > 40) have been associated with deterioration of renal function in children with myelomeningocele. For these children, careful pressure management preserves renal function. However, similar evidence is lacking in adult congenital urology (ACU) patients with NGB. We describe renal functional outcomes of non-surgical management of adults with dLPP > 40 or premicturition detrusor pressure (PMDP) >40 cm H2 O, consisting of close follow-up with urodynamic studies (UDS) and renal ultrasound (RUS), paired with adjustments to clean intermittent catheterization (CIC) frequency, anticholinergics, and addition of onabotulinumtoxinA toxin (BTX) injection...
