Multiple urinary bladder calculi: a rare cause of irreducible uterovaginal prolapse

A case of irreducible prolapse with multiple bladder calculi in a 65-years-old multiparous, postmenopausal woman is reported. Inability to walk, constipation and urinary incontinence were her primary complaints. Routine ultrasound of the abdomen and pelvis failed to reveal multiple vesical calculi as the prolapse was lying outside the pelvis. However, targeted plain X-ray of the prolapsed mass showed multiple vesical calculi. The patient was managed with single-stage vaginal hysterectomy and laparotomy. First vaginal hysterectomy was done then prolapsed cystocele was reduced and extraperitoneal vesicolithotomy done. Currently, the patient is relieved of all symptoms. Management of an irreducible procidentia and a hard mass in the anterior compartment, as in this case, can be challenging and requires a diligent effort to confirm the diagnosis and to execute the appropriate surgical protocol to achieve optimal outcome with minimal intra- and post-operative complications.

Development and Validation of a Nomogram for Predicting Bladder Calculi Risk in Patients With Benign Prostatic Hyperplasia

Objective To develop and validate a nomogram for predicting bladder calculi risk in patients with benign prostatic hyperplasia (BPH).Methods A total of 368 patients who underwent transurethral resection of the prostate (TURP) and had histologically proven BPH from January 2018 to January 2021 were retrospectively collected. Eligible patients were randomly assigned to the training and validation datasets. Least absolute shrinkage and selection operator (LASSO) regression was used to select the optimal risk factors. A prediction model was established based on the selected characteristics. The performance of the nomogram was assessed by calibration plots and the area under the receiver operating characteristic curve (AUROC). Furthermore, decision curve analysis (DCA) was used to determine the net benefit rate of of the nomogram. Results Among 368 patients who met the inclusion criteria, older age, a history of diabetes and hyperuricemia, longer intravesical prostatic protrusion (IPP)and larger prostatic urethral angulation (PUA) were independent risk factors for bladder calculi in patients with BPH. These factors were used to develop a nomogram, which had a good identification ability in predicting the risk of bladder calculi in patients, with AUROCs of 0.911 (95% CI: 0.876–0.945) in the training set and 0.884 (95% CI: 0.820–0.948) in the validation set. The calibration plot showed that the model had good calibration. Moreover, DCA indicated that the model had a goodclinical benefit. Conclusion We developed and internally validated the first nomogram to date to help physicians assess the risk of bladder calculi in patients with BPH, which may help physicians improve individual interventions and make better clinical decisions.

Endourological management of multiple large bladder calculi over eroded mesh in an adult with augmented bladder and catheterisable continent appendicovesicostomy

Migration of abdominal wall mesh in an augmented bladder is a rarely encountered complication leading to formation of bladder stones causing recurrent urinary tract symptoms. The usual management of this condition involves either open surgical or a percutaneous approach for removal of the stone and migrated portion of mesh. Diagnosis of a migrated mesh is usually made intraoperatively during cystolitholapaxy. Appropriate management results in symptomatic improvement. Endoscopic management through catheterisable continent appendicovesicostomy has not been described to manage this challenging condition. To the best of our knowledge, we describe herewith the first report of endoscopic management of a large bladder stone formed over migrated mesh which involved removal of migrated mesh with holmium laser via a Mitrafanoff.

Application of Percutaneous Holmium Laser Lithotripsy in the Treatment of Bladder Calculi with Lower Urinary Tract Obstruction or Pelvic Joint Disease

<b><i>Objective:</i></b> The aim was to summarize the experience of percutaneous holmium laser lithotripsy in the treatment of bladder calculi with lower urinary tract obstruction or pelvic joint disease in our hospital, explore its efficacy and safety, and improve the minimally invasive surgical technique for bladder calculi. <b><i>Methods:</i></b> The clinical data of 61 patients with bladder calculi combined with lower urinary tract obstructive diseases, including urethral stricture, benign prostatic hyperplasia, and bladder neck contracture or pelvic joint diseases in our hospital from 2017 to 2019 were retrospectively analyzed. All patients with bladder stones measuring 1.5–9 cm were placed in supine or lithotomy position. B-scan was conducted to locate the puncture above the pubic symphysis, establishing a 16–30 Fr bladder channel, and Lumenis holmium laser lithotripsy was subsequently performed through a Li Xun Nephroscope. The crushed stones were flushed out through the percutaneous bladder channel or taken out with foreign body forceps. After surgery, the cystostomy tube was indwelled for 3 days. <b><i>Results:</i></b> All the 61 cases were operated successfully with an average lithotripsy time of 25 min, and there was no conversion to open surgery. Postoperative reexamination showed neither residual calculi nor complications such as severe infection, massive hemorrhage, and intestinal injury. <b><i>Conclusion:</i></b> Percutaneous holmium laser lithotripsy is an improved minimally invasive surgical technique for the treatment of bladder calculi with the advantages of clear surgical field, high stone removal efficiency, less trauma, low-pressure bladder perfusion, and low incidence of accessory injury and infection. For patients with lower urinary tract obstructive disease resulting in obstruction of transurethral surgery and patients with pelvic joint disease resulting in difficult lithotomy position placement, this procedure is more advantageous than transurethral surgery. It is also suitable for bladder calculus with a long diameter &#x3e;5 cm or multiple calculi.

Table Sugar and Salt for the Reduction of Incarcerated Prolapse with Vescical Calculi- A Case Report

Incarcerated prolapse in association with bladder calculi is a rare occurrence. Table sugar and salt, which are both hygroscopic agents, have been used to reduce incarcerated bowel prolapse. Table sugar and salt was used in the following case of incarcerated procidencia with vescical calculi. Cystotomy with bladder stone removal was done by abdominal route. Total abdominal hysterectomy with bilateral salpingoopherectomy was done with pelvic floor repair and vault suspension.
