A 48-year-old man admitted to the urology outpatient clinic with major symptoms of right-side pain and intermittent lower urinary tract symptoms (LUTSs) such as low urine flow rate, dysuria, and frequency. Uroflowmetry showed low urine flow, and laboratory tests revealed no pathology. Ultrasound (US) showed a 7 cm calcific mass above the bladder and a kidney cyst with a diameter of 5.3 cm in the upper pole of the right kidney. Enhanced computed tomography confirmed the US findings. Laparoscopic transperitoneal renal cyst decortication was performed...

Forty-nine patients with stage IIb cervical cancer were included to investigate the changes in bladder volume in response to different approaches to maintaining consistent bladder filling. The impacts of age (P age), water consumption (P wat ), and body mass index (BMI, P bmi ) on the mean urinary inflow rate (v tot ) were analysed. The bladder volume (BV) increased linearly over time. A large variation in v tot among individuals was observed, ranging from 0.19 to 5.13 ml/min. The v tot was correlated with P age (R = -0...

INTRODUCTION: Isolated bilateral simplex ectopic ureters (BSEUs) are rare but pose a therapeutic challenge: ureteric reimplantation alone does not accomplish continence in all. Identifying the patients needing additional procedures for continence early could prevent multiple operations. OBJECTIVE: Potential preoperative indicators for postoperative continence are explored in eight BSEU girls without cloacal, anorectal, or spinal anomalies. STUDY DESIGN: With institutional approval, all patients with BSEU between 1985 and 2012 were retrospectively reviewed...

Sonography is a convenient, non-invasive diagnostic modality in small ruminants, often used in reproductive management, internal medicine, and surgery. Pregnancy diagnostics and imaging anatomy and pathology of organs, such as neoplasia, are major applications. Urolithiasis is one of the most common causes of death in male sheep and goats, for which sonography is the diagnostic modality of choice. Although ultrasound-imaging techniques for kidneys, ureters, and urinary bladder in small ruminants have been described previously, this study focuses on reporting the imaging technique of the extra-pelvic portion of the urethra, as nearly all the cases of obstructive urolithiasis result from urinary stones in this part...

A 34-year-old para V woman was referred to our centre at 35+1 weeks of gestation for an assumed fetal malformation with prenatal renal impairment and anhydramnios. Prenatal ultrasound demonstrated unilateral renal agenesis; the bladder was not detectable. The baby was born by caesarian section at 36+2 weeks of gestation because of placental insufficiency. Postnatal adaptation was uneventful, but the newborn presented external stigmas of trisomy 21 and progressive renal impairment with anuria. Nevertheless, the postnatal ultrasound showed two enlarged kidneys in loco typico with impaired perfusion but without signs of malformations...

Müllerianosis of the bladder is an extremely rare and highly symptomatic bladder tumour comprising of at least two types of Müllerian derived tissues. We present the case of a 59-year-old woman presenting with painful macroscopic haematuria associated with urgency, frequency and incontinence. She is a nulliparous postmenopausal woman without malignancy risk factors or previous abdominal surgery. Initially identified on ultrasound scan, she was taken for transurethral resection of bladder tumour (TURBT). Histology confirms the diagnosis...

Residual bladder volume measurement is a very important marker for patients with urinary retention problems. To be able to monitor patients with these conditions at the bedside by nurses or in an out patient setting by general physicians, hand held ultrasound devices will be extremely useful. However to increase the usage of these devices by non traditional users, automated tools that can aid them in the scanning and measurement process will be of great help. In our paper, we have developed a robust segmentation algorithm to automatically measure bladder volume by segmenting bladder contours from sagittal and transverse ultrasound views using a combination of machine learning and active contour algorithms...

PURPOSE OF REVIEW: To assess the contemporary literature on the prevalence, cause and management of lower urinary tract symptoms (LUTS) and bladder overactivity following treatment of prostate cancer with radical surgery, radiotherapy and minimally invasive therapies for localized prostate cancer, including cryotherapy and high-intensity focused ultrasound (HIFU). RECENT FINDINGS: Generally, the highest risk of urinary incontinence is after open radical prostatectomy (7-40%), although not all contemporary studies demonstrate a difference between open and laparoscopic techniques...

REVIEW
Matthew J Kaptein, Elaine M Kaptein
We propose that renal consults are enhanced by incorporating a nephrology-focused ultrasound protocol including ultrasound evaluation of cardiac contractility, the presence or absence of pericardial effusion, inferior vena cava size and collapsibility to guide volume management, bladder volume to assess for obstruction or retention, and kidney size and structure to potentially gauge chronicity of renal disease or identify other structural abnormalities. The benefits of immediate and ongoing assessment of cardiac function and intravascular volume status (prerenal), possible urinary obstruction or retention (postrenal), and potential etiologies of acute kidney injury or chronic kidney disease far outweigh the limitations of bedside ultrasonography performed by nephrologists...

AIMS: The ultrasound assessment of bladder wall thickness (BWT) and intravesical prostatic protrusion (IPP) have emerged as a non-invasive, inexpensive, time-saving alternatives to pressure-flow studies to assess benign prostatic obstruction (BPO). Aim of our study was to evaluate the effect on detrusor mass of dutasteride add-on therapy in men with lower urinary tract symptoms (LUTS) and benign prostatic enlargement (BPE). METHODS: A consecutive series of BPE patients with a prostate volume (PV) ≥30 mL and an international prostate symptoms score (IPSS) ≥8 not satisfied with Tamsulosin monotherapy were enrolled...

BACKGROUND Intradiverticular bladder tumors are rare. This renders diagnosis of an intradiverticular bladder tumor difficult. Imaging plays a vital role in achieving the diagnosis, and subsequently staging of the disease. CASE REPORT A 74-year-old male presented to our center with a few months history of constitutional symptoms. Upon further history, he reported hematuria two months prior to presentation, which stopped temporarily, only to recur a few days prior to coming to the hospital. The patient admitted to having lower urinary tract symptoms...

BACKGROUND: Schistosoma haematobium infections are responsible for significant urinary tract (UT) complications. Schistosomiasis control programs aim to reduce morbidity, yet the extent of morbidity in preschool-aged children and the impact of treatment on morbidity reduction are not well studied. METHODOLOGY: Our study was embedded in a randomized, placebo-controlled, single-blind trial in Côte d'Ivoire, which evaluated the efficacy and safety of three doses (20, 40 and 60 mg/kg) of praziquantel in school-aged (SAC) and preschool-aged (PSAC) children infected with S...

INTRODUCTION: High-grade vesicoureteral reflux (VUR) in children is associated with recurrent urinary tract infection (UTI) and renal damage. Breakthrough UTI despite continuous antibiotic prophylaxis (CAP) during the first years of life is a matter of concern and evokes early intervention. We investigated whether early endoscopic treatment (ET) of VUR grade 4-5 can reduce the risk of UTI recurrence and renal scarring. MATERIALS AND METHODS: This prospective, randomized, controlled, multicentre, 1-year follow-up trial comprised 77 infants, <8 months of age with VUR grade 4-5 (Table) randomized to CAP (n = 39) or ET (with prophylaxis until resolution) (n = 38)...

INTRODUCTION: The proactive management of children with myelomeningocele (MMC) has contributed to decreasing their progression to end-stage renal disease, thanks to early urological evaluation and timing implementation of treatments. OBJECTIVE: To demonstrate that early urological evaluation of the urinary tract in MMC shows functional alterations in most cases, and that it requires medical intervention, even when in some cases the complementary imaging studies do not show any abnormalities...

INTRODUCTION AND HYPOTHESIS: The majority of patients with cystocele undergoing reconstructive surgery have combined defects of pubocervical fascia and uterosacral/cardinal ligament complex. In this regard, the simultaneous correction of both defects is rational. Furthermore, decreasing the use of synthetic materials in pelvic floor surgery is an important goal. The aim was to evaluate the objective and subjective cure rate of a hybrid technique: bilateral sacrospinous fixation using modern monofilament synthetic tape (apical sling) combined with the original technique of subfascial colporrhaphy...

INTRODUCTION: Uterine lipoleiomyomas are a rare type of uterine myomas, which have been seldom diagnosed and are less known and still unusual. Histologically they are composed of smooth muscle cells with multiple fat cells and fibrous tissue. Their pathogenesis is still a stigmata and their preoperative diagnosis is still questionable. CASE REPORT HISTORY: A 39-year old woman presented at the University clinic for obstetrics and gynecology with complaints of a mild low abdominal and pelvic pain, increased frequency of vaginal bleeding and abdominal distension...
