The effects of drinking bicarbonate-rich mineral water in calcium oxalate stone formers: an open label prospective randomized controlled study in an Asian cohort.

Purpose: To examine the effects of drinking bicarbonate-rich mineral water in patients with calcium oxalate stones.

Materials And Methods: This was an open label prospective randomized controlled study comparing the effects of a bicarbonate-rich mineral water versus plain water on urine biochemistry in patients with calcium oxalate stones. The mineral water group were instructed to consume 1.

Mini versus ultra-mini percutaneous nephrolithotomy in a paediatric population.

Objective: To evaluate whether there would be a difference in outcome when the smaller ultra-mini 12 Fr sheath was used instead of the mini 16 Fr sheath for percutaneous nephrolithotomy (PCNL) in paediatric patients for stones less than 25 mm.

Methods: This was a prospective cohort study of patients who underwent PCNL in our hospital in a 2-year period from July 2016 to June 2018 by a single surgeon. PCNL was performed in a prone position and tract was dilated to the respective size using single step dilatation.

The clinical outcomes of laser with suction device in mini-percutaneous nephrolithotomy.

Objective: To evaluate the safety, efficacy and feasibility of laser with suction device in mini-percutaneous nephrolithotomy (mini-PCNL).

Methods: A retrospective study was conducted including 200 patients who underwent mini-PCNL for renal stones. All patients underwent PCNL using Electro-Medical Systems laser.

Iatrogenic bladder injury from port insertion during laparoscopic appendicectomy.

A 26-year-old man underwent laparoscopic appendicectomy for acute appendicitis that was carried out uneventfully after initial urethral catheterisation to empty the bladder. Postoperatively, he developed oliguria associated with high drain output and elevated drain fluid creatinine. A contrast-enhanced computed tomography urography scan showed a small amount of contrast in the intraperitoneal space.

Patients with small prostates and low-grade intravesical prostatic protrusion - A urodynamic evaluation.

Objective: Despite high-grade intravesical prostatic protrusion (IPP) being closely related to bladder outlet obstruction (BOO), up to 21% of patients with low IPP remain obstructed. This study evaluates the characteristics and urodynamic findings of men with small prostates and low IPP.

Methods: One hundred and fourteen men aged >50 years old with lower urinary tract symptoms (LUTS) were assessed with symptoms, uroflowmetry, serum prostate-specific antigen (PSA), transabdominal ultrasound measurement of prostate volume (PV), IPP and post-void residual urine (PVRU).

Early outcome of transurethral enucleation and resection of the prostate versus transurethral resection of the prostate.

Introduction: Recurrent prostate adenoma is a long-term complication following transurethral resection of the prostate (TURP). Transurethral enucleation and resection of the prostate (TUERP) is more appealing, since the nodular adenoma can be completely removed through endoscopy. TUERP is also hypothesised to result in a lower frequency of recurrent adenoma.

The clinical presentation and diagnosis of ketamine-associated urinary tract dysfunction in Singapore.

Ketamine is a short-acting anaesthetic agent that has gained popularity as a 'club drug' due to its hallucinogenic effects. Substance abuse should be considered in young adult patients who present with severe debilitating symptoms such as lower urinary tract symptoms, even though the use of controlled substances is rare in Singapore. Although the natural history of disease varies from person to person, a relationship between symptom severity and frequency/dosage of abuse has been established.
