The Distribution of Post-Void Residual (PVR) Volumes in People Seeking Care in the Symptoms of Lower Urinary Tract Dysfunction Network (LURN) Observational Cohort Study with Comparison to Asymptomatic Populations
To describe the distribution of post-void residual (PVR) volumes across patients with and without lower urinary tract symptoms (LUTS) and examine relationships between self-reported voiding symptoms, storage symptoms, and PVR.
To report success and patient reported urinary and sexual outcomes of patients who underwent anastomotic urethroplasty and dorsal buccal onlay urethroplasty.
To evaluate the histopathological correlation of recently described subclassification of Bosniak category 3 cysts (3s and 3n).
To determine whether frailty is associated with increased odds of 30-day surgical complications among men undergoing both artificial urinary sphincter (AUS placement and removal procedures and to determine whether frailty was associated with increased odds of having an AUS removal procedure.
A 73 year-old male patient presented with a history of moderate LUTS, namely frequency, nocturia and weak urinary stream. He had no history of previous surgery, or any medical conditions of notice, and he is a non-smoker, nonalcoholic. He has been diagnosed with benign prostate hyperplasia (BPH) ten years before, for which he was then being treated with dutasteride and tansulosin. Because of having slightly elevated PSA, which had been stable at 6ng/mL over the past years, the patient had also undergone to two twelve-core transrectal ultrasound guided (TRUS) biopsies.
Penetrating perineal trauma is an unusual urologic injury. Even less common is a delayed presentation. Herein we present the case of a patient with delayed development of a corporal cutaneous fistula three months following perineal trauma.
Malignant neoplasm arising from ileal ureter used for ureteral reconstructive surgery is an exceedingly rare event. Ureteroileoplasty was being performed since the beginning of the last century, but it was described more extensively in literature during the 1950s.1,2 Recurrent urinary infections, chronic renal failure, urolithiasis, anastomotic stricture, metabolic acidosis and chronic dilation of the graft had been described as late complications of ureteroileoplasty.3,4 Herein, we describe history, imaging and pathologic findings of a small bowel adenocarcinoma arising from ileal ureter in a woman of 78 year-old, subjected to ureteroileoplasty about forty years earlier.
A 69-year-old male with no documented past medical history presented to an outside institution with a 2.9 cm left lower pole renal mass that was incidentally discovered on imaging performed for abdominal and back pain. He denied any history of hematuria or flank pain. He was referred to the interventional radiology service for CT-guided percutaneous biopsy and cryoablation of the left renal mass. Three core needle biopsies were performed using a 20 gauge cutting needle with coaxial technique. Hydrodissection was used to displace the colon in preparation for cryoablation due to the lesion's anterior location.
International and Multi-Institutional Assessment of Factors Associated with Performance and Quality of Lymph Node Dissection during Radical Nephrectomy
To determine factors associated with performance and quality of lymph node dissection during radical nephrectomy.
To examine the recent epidemiology of pediatric urinary stone disease (USD) in the United States.
To quantify the use of downstream studies following staging bone scans in patients with muscle-invasive bladder cancer. Bone scans may be obtained in high-risk bladder cancer patients prior to radical cystectomy to exclude bone metastases. However, false positive bone scans can occur, resulting in the need for additional studies.
We read with interest the recent article by Abboud et al1 regarding ovarian malignancy in women after radical cystectomy (RC). The authors demonstrate a low rate of subsequent ovarian malignancy, and conclude that oophorectomy at the time of RC may be omitted. While we applaud the goal to spare the undesirable morbidity of oophorectomy, we suggest a pause to blanket implementation of this recommendation.
OVOTESTICULAR DISORDER OF SEX DEVELOPMENT: A RARE CASE OF LATERAL SUBTYPE 45X/46XY KARIOTYPE DIAGNOSED IN ADULTHOOD
A 53-year-old male referred to our Centre because of hypergonadotropic hypogonadism detected during urological follow-up for urethral lithiasis. Physical Examination showed short stature, micropenis, ambiguous external genitalia, normal secondary sexual characteristics. Karyotype: 45 × 0/46XY. Abdominal MRI revealed the presence of uterus-like structure, right annex and left testes without prostate. He underwent laparoscopic removal of dysgenetic tissues; histological examination confirmed the presence of little uterus, fallopian tubes, little atrophic ovary, and vaginal tract; left testes was atrophic with sclero-jalinosis of seminal tubes and Leydig's cells hyperplasia.
To evaluate the feasibility and outcomes of full thickness penile skin grafting (FTSG) for phalloplasty during acquired buried penis repair.
To assess if 'tumour budding' (TB) behaves as a poor prognostic factor in muscle-invasive bladder carcinoma (MIBC). TB is the presence of tumour cells isolated or in small groups of fewer than five cells located at the tumour invasion front.
To evaluate the genetic and environmental relationship among prostatitis and other urological conditions, including benign prostatic hyperplasia (BPH) and prostate cancer (CaP), a classical twin design and biometric modeling was used. While prostatitis – characterized by pain and voiding symptoms, no clear etiology, and functional and quality of life impairments – co-occurs with other urinary conditions, the degree of shared overlapping etiological processes among them remains unclear. We examined the contribution of genetic and environmental factors to these conditions and the etiology of their associations at the level of genetic and environmental influences.
Prostate-specific-membrane-antigen (PSMA) is a transmembrane protein with significantly increased expression in the cells and metastases of prostate carcinoma (PCa). PSMA-expression correlates with higher serum levels of prostate-specific-antigen (PSA) and a higher Gleason Score (GS). This finding has led to the development of novel imaging modalities such as 68Ga-/18F-labeled PSMA PET/CT and PET/MRI. This article reviews the literature pertaining to various new imaging technologies for the management of PCa.
The Incidence and Durability of Compensatory Hypertrophy in Pediatric Patients with Solitary Kidneys
To evaluate the incidence and durability of compensatory hypertrophy with solitary kidneys in the setting of those with multicystic dysplastic kidney or Wilms tumor status post nephrectomy.
Second reported case of pediatric bladder alveolar soft part sarcoma as secondary malignancy after prior cytotoxic chemotherapy
Alveolar soft part sarcoma (ASPS) is a rare malignancy with high rates of metastasis at presentation, defined by an unclear cellular origin and a unique unbalanced ASPSCR1-TFE3 translocation (der(17)t(X:17)(p11:q25))1. ASPS is insensitive to chemotherapy and has been reported to involve the bladder only twice in the pediatric literature; once as a primary malignancy2, and once as a secondary malignancy after cytotoxic chemotherapy3. Herein, we report the third case of pediatric bladder ASPS in a female patient who received cytotoxic chemotherapy for low-risk neuroblastoma.
Use of Office Versus Ambulatory Surgery Center Setting and Associated Ancillary Services on Healthcare Cost Burden for Vasectomy Procedures
To analyze variation in total healthcare costs for vasectomies performed in the United States, based on procedure setting and use of ancillary pathology services.
