Infravesical obstruction

N V Kriuchkova, M I Kogan, V P Glukhov, V V Mitusov, D V Sizyakin
Benign prostatic hyperplasia (BPH) is one of the most common diseases of men elderly and senile age. The main surgical methods of treatment for BPH are transurethral resection and open prostatectomy. In some cases surgical treatment of BPH is accompanied by the development of postoperative complications leading to recurrence of the infravesical obstruction. Currently, there are no strict guidelines for selection of an optimal method of correction of late obstructive complications. This study highlights the main existing theories concerning development of urethral strictures and bladder neck contracture...

BACKGROUND: Posterior urethral valves (PUVs) constitute the most common infravesical urinary obstruction in boys and are often accompanied by severe consequences to the lower and upper urinary tract. Currently, about two-thirds of diagnosis of PUVs has been suspected by prenatal ultrasonography findings. The aim of this study was to compare long-term clinical outcomes in two groups of patients with PUVs, with antenatal vs. postnatal diagnosis. STUDY DESIGN: This was a retrospective cohort study of 173 patients with PUVs systematically followed up in a tertiary center...

BACKGROUND: The impact of number of endoscopic enucleation of the prostate techniques (holmium laser enucleation - HoLEP for example) on erectile function have already been investigated. However, the thulium-fiber laser, in this setting remains unstudied. In this study, we compared sexual function outcomes in patients with benign prostatic hyperplasia (BPH) treated with transurethral resection of the prostate (TURP) or thulium-fiber laser enucleation (ThuFLEP). METHODS: We performed a retrospective analysis of patients who underwent transurethral resection and endoscopic enucleation of the prostate for BPH; inclusion criteria was the presence of infravesical obstruction (IPSS > 20, Qmax < 10 mL/s)...

INTRODUCTION: Various authors argued that the voiding urgency component in mixed urinary incontinence (MUI) is different than urge urinary incontinence (UUI). In this last case they suggest that incontinence in MUI could be overdiagnosed in patients with SUI, misunderstanding the leak as UUI. OBJETIVES: To evaluate clinical and urodynamic characteristics of patients with MUI and pure UUI. METHODS: A retrospective study of our urodynamics database was performed evaluating 450 women with MUI and UUI...

INTRODUCTION: The current standard of surgery for benign prostatic hyperplasia (BPH) greater than 80 cm3 includes open adenomectomy and holmium enucleation. Transurethral resection and laser vaporization are second line interventions, while the role of laparoscopic extraperitoneal adenomectomy is not fully understood. AIM: To evaluate the role of laparoscopic technique as a surgical modality for BPH greater than 80 cm3. MATERIALS AND METHODS: This study retrospectively evaluated the results of 79 patients (mean age 68 years) who underwent transcapsular extraperitoneoscopic adenomectomy from 2011 to 2016...

RELEVANCE: Benign prostatic hyperplasia (BPH) is one of the most common urologic diseases of males. In patients who failed drug therapy of lower urinary tract symptoms (LUTS) caused by BPH, the most important indication for surgery is the presence of infravesical obstruction (IVO). IVO is detected by pressure-flow studies and is characterized by high detrusor pressure with decreased urinary flow rate. The invasiveness and high cost of this investigation has stimulated a search for non-invasive techniques that could reliably characterize the presence of IVO secondary to BPH...

INTRODUCTION: The estimated recurrence rate of benign prostatic hyperplasia (BPH) after transurethral resection of the prostate is about 5 to 15%. Laser enucleation of the prostate results in a much lower recurrence rate (not exceeding 1-1.5%). At the same time, laser enucleation of the prostate is still not widely used for recurrent prostatic hyperplasia since it believed to be technically difficult in cases. AIM: To describe the distinctive features of thulium and holmium laser enucleations of the prostate in the management of recurrent BPH and show that the technical difficulties are not an obstacle to the wide application of this technique...

Infravesical obstruction (IVO) is an important characteristic of the functional state of male lower urinary tract. It is believed that IVO confirmed by pressure-flow study findings warrants switching from a medical to surgical management of lower urinary tract symptoms (LUTS). Intravesical prostatic protrusion (IPP) is a new indicator for detecting IVO secondary to benign prostatic hyperplasia (BPH). This indicator has several advantages over other non-invasive methods for evaluating IVO. The initial findings on the relationship between IPP and IVO suggest the feasibility of its clinical use as a screening tool in men with obstructive voiding symptoms...

OBJECTIVE AND INTRODUCTION: Cowper's syringocele is a cystic dilation of the bulbourethral gland duct, initially defined by Maizels et al. in 1983. Although obstructive and non-obstructive types of this rare anomaly are described, clinical symptoms are highly unspecific. Therefore, we report 12 cases of children and young adults diagnosed with Cowper's syringocele to further clarify clinical course, comorbidity and treatment strategies. STUDY DESIGN: We retrospectively collected clinical data of 12 children and young adults from birth to 18...

The therapeutic effect of doxazosin (40 μg/kg/day over one month) on urinary bladder was examined in female rats with modeled chronic infravesical obstruction (IVO) produced by graduated mechanical constriction of the proximal urethral segment. In one month, IVO induced a pronounced vesical hypertrophy both in treated and untreated rats that manifested in increased bladder weight and capacity, the latter increment being pronouncedly greater in treated rats. In untreated IVO rats, infusion cystometry revealed elevated basal intravesical pressure of void bladder P0, markedly increased maximal (premicturitional) pressure Pmax, and increased amplitude of spontaneous oscillations of intravesical pressure ΔPdet in filled bladder...

BACKGROUND: Urethral valves are infravesical congenital anomalies, with the posterior urethral valve (PUV) being the most prevalent one. Anterior urethral valve (AUV) is a rare but a well-known congenital anomaly. AUV and diverticula can cause severe obstruction, whose repercussions on the proximal urinary system can be important. Few cases have been described; both separately and in association with urethral diverticulum. The presentation of such a rare but important case led us to a report with highlighting its classic imaging features...
