Long-term risks of childhood surgery.

INTRODUCTION: Several patients, who underwent major reconstruction under the care of an experienced pediatric urologist are now, as adults, several years later, appearing with long term problems and complications. This consensus process was undertaken to give an overview of long term consequences (and their management) of urological childhood surgery. MATERIAL AND METHODS: Several known urologists with experience in life-long follow up and revisional surgery of patients with congenital conditions were asked to review literature and comment based on their experience about several complications of childhood surgery. RESULTS: Renal impairment, metabolic consequences, bladder stones, Vit B 12 deficiency and recurrent infections are often encountered. Also recurrent ureteric strictures and difficulties with catheterizable channel (both obstruction and incontinence) can be challenging to manage. Specific attention is needed regarding female sexuality and pregnancy. Both the development of malignancies in reconstructed bladders as secondary malignancies need to be taken into account during follow up. CONCLUSION: Follow up of patients with rare congenital conditions is highly specialized and revisional surgery can be challenging. Therefore, follow up needs to be organized in specialized centers.

An observational study on the sexual, genital and fertility outcomes in bladder exstrophy and epispadias patients.

INTRODUCTION: Bladder exstrophy and epispadias complex (BEEC) is a spectrum of congenital malformations ranging from an isolated epispadias to a full exstrophy. It is an uncommon disease and little is known on how patients cope with its implications later in life. OBJECTIVE: The goal of this study is to assess the sexual, continence and fertility outcomes of BEEC patients, who had reconstructive bladder surgery during childhood. Considering the sensitive nature of these topics, they are not easily spoken about in the doctor's office. Our aim is to shed some light on possible points of improvement in follow-up. STUDY DESIGN: 63 patients between 18 and 45 years old were sent an electronic questionnaire based on previous existing standardized questionnaires. They were asked about sexual and psychosexual wellbeing, urinary incontinence and fertility. Data from their medical files (medical history on previous surgeries). and questionnaire answers are linked through an anonymous subject number and put into an Excel file for descriptive representation. RESULTS: 22 men and 8 women filled in the questionnaire. All but 2 are sexually active. Reasons to avoid sexual activity are equally divided as BEEC-related and non-BEEC-related. Sexual satisfaction is lower in the male group due to problems with erection, ejaculation, condom usage and embarrassment about physical appearance. In females problems concerning pain and reaching orgasm are mentioned. 30% report depressive feelings. There is a clear correlation between number of reconstructive surgeries and sexual satisfaction. 90% of patients urinate via catheterization, mostly through a Mitrofanoff connection. This leads to complications such as foul odors, infection, embarrassment and sexual dysfunction. 8 out of 13 men conceived a child (with the use of their own sperm), 2 out of 4 women did. DISCUSSION: A strength of this study is the use of standardized questionnaires which allow comparison to a control patient group. Our study is one of the first to show how patients cope with the challenges of BEEC by the use of open questions. We see an overall high quality of life yet an important impact on mental health. CONCLUSION: BEEC is associated with many challenges in the adult life of patients. A more holistic and interdisciplinary approach is needed to include sensitive topics in long term follow-up.

14F Super-Mini Percutaneous Cystolitholapaxy: A Novel Technique in the Treatment of Bladder Stones.

Introduction: This single-center experience describes the indications, novel technique, and outcomes of performing 14F super-mini percutaneous cystolitholapaxy (14F-SMPCCL). Materials and Methods: Cases between 2019 and 2022 were retrospectively identified with surgical outcomes recorded. Using percutaneous access to the bladder, an endoscope was inserted through the ClearPetra 14F super-mini sheath and laser lithotripsy completed with stone fragments suctioned out. Results: Sixteen cases were included in the study and all patients were adults. Average conglomerate stone size was 28.1 mm (range = 10-50 mm). Average operative time was 60.0 minutes (range = 23-110 minutes). Visual stone-free rate was 91.7%, radiologic stone-free rate was 81.3%, and average postoperative length of stay was 1 day. One patient developed urosepsis postoperatively and there were no other complications. Conclusion: The novel technique of 14F-SMPCCL is safe and feasible for treating large burdens of bladder stones with a conglomerate size of ∼2.5 to 5 cm. Active suction allows for efficient removal of stone fragments.

Asymptomatic ureteral rupture secondary to chronic urinary retention from massive prostatic enlargement.

Non-traumatic ureteral rupture has been reported more frequently, resulting from increased intraluminal pressures from distal urinary tract obstruction. We report the case of a 77-year-old man presenting with chronic urinary retention secondary to massive prostatic enlargement through acute kidney injury. Ultrasound scan detected a shallow left perinephric fluid collection with a possible bladder mass, demonstrated on flexible cystoscopy to be a massive median lobe of prostate. Computed tomography confirmed extravasation of urine from the left proximal ureter. In the absence of specific symptoms, the patient had successful conservative management with antibiotics and urinary catheterization for his acute episode, although declined further surgical intervention.

Superoxide constricts rat pulmonary arteries via Rho-kinase-mediated Ca(2+) sensitization.

Reactive oxygen species play a key role in vascular disease, pulmonary hypertension, and hypoxic pulmonary vasoconstriction. We investigated contractile responses, intracellular Ca(2+) ([Ca(2+)](i)), Rho-kinase translocation, and phosphorylation of the regulatory subunit of myosin phosphatase (MYPT-1) and of myosin light chain (MLC(20)) in response to LY83583, a generator of superoxide anion, in small intrapulmonary arteries (IPA) of rat. LY83583 caused concentration-dependent constrictions in IPA and greatly enhanced submaximal PGF(2alpha)-mediated preconstriction. In small femoral or mesenteric arteries of rat, LY83583 alone was without effect, but it relaxed a PGF(2)alpha-mediated preconstriction. Constrictions in IPA were inhibited by superoxide dismutase and tempol, but not catalase, and were endothelium and guanylate cyclase independent. Constrictions were also inhibited by the Rho-kinase inhibitor Y27632 and the Src-family kinase inhibitor SU6656. LY83583 did not raise [Ca(2+)](i), but caused a Y27632-sensitive constriction in alpha-toxin-permeabilized IPA. LY83583 triggered translocation of Rho-kinase from the nucleus to the cytosol in pulmonary artery smooth muscle cells and enhanced phosphorylation of MYPT-1 at Thr-855 and of MLC(20) at Ser-19 in IPA. This enhancement was inhibited by superoxide dismutase and abolished by Y27632. Hydrogen peroxide did not activate Rho-kinase. We conclude that in rat small pulmonary artery, superoxide triggers Rho-kinase-mediated Ca(2+) sensitization and vasoconstriction independent of hydrogen peroxide.
