Managing intractable haematuria is a daunting task. One cause of this condition is radiationinduced
haemorrhagic cystitis. Several treatments for the condition have been proposed and one
non-invasive option is alum irrigation. Here, we report on a 65-year-old woman with intractable
haematuria secondary to radiation cystitis who was successfully treated with alum irrigation. Alum
irrigation is safe, well tolerated and relatively cheap. A review of the literature and a comprehensive
discussion on alum irrigation as treatment for haematuria is discussed here to create an awareness
regarding this treatment option.

Nutrition has been widely recognized to have certain levels of influence on the risk of kidney stone formation. Thus, this case-control study was conducted to determine the association of dietary intake and lifestyles factors with kidney stone disease. Sociodemographic data, dietary intake, supplements intake, smoking and alcohol habit, medical history, physical activity and anthropometric data were obtained using interviewer-administered pre-tested questionnaires among 81 patients who had been diagnosed with kidney stone disease and 81 patients without kidney stone disease at Universiti Kebangsaan Malaysia Medical Centre. The results indicated that body mass index and hip circumference were higher among cases as compared to controls in both men and women (p < 0.05). Energy, macronutrients and micronutrients intake were higher for case subjects compared to control subjects for all significant parameters (p < 0.05). Results showed positive association of kidney stone with consumption of nuts (≥1 time/week) for men and women while consumption of eggs (1-3 times/month) and beans (1-6 times/week) showed positive association for women. Analysis of multivariate found the risk factor among women was diabetes mellitus [Adjusted OR = 27.6 (95% CI = 1.43-53.3)]
(p < 0.05). Whilst, plain water intake of at least 6 glasses [Adjusted OR = 0.001 (95% CI = 0.000-0.08)] (p < 0.05) and 8 glasses per day [Adjusted OR = 0.001 (95% CI = 0.000-0.02)] (p < 0.05) reduced the risk among women. The risk factors for men were smoking habits [Adjusted OR = 16.2 (95% CI = 1.29-203)] (p < 0.05), consumption of carbonated drink 1-3 times per month [Adjusted OR = 6.25 (95% CI = 1.04-40.7)] (p < 0.05) and 1-6 times per week [Adjusted OR = 12.5 (95% CI = 1.41-111)] (p < 0.05). Unhealthy dietary and lifestyles factors increased the risk of kidney stone disease and various risk factors were found for different sexes.

Background: Acute urinary retention (AUR) is one of the most serious complications of benign prostatic hypertrophy. This study was done to predict the outcome of trial of voiding without catheter (TWOC) in patients with AUR with intravesical prostatic protrusion (IPP) detected on transabdominal ultrasound. Other factors such as prostatic volume and patient’s age were also assessed.
Method: Patients with a first episode of AUR secondary to benign prostatic hypertrophy were assessed with ultrasound following bladder catheterization. The IPP was measured and graded (grade 1 is 5 mm or less, grade 2 is 5–10 mm and grade 3 is more than 10 mm). Success of TWOC was then correlated with the degree of IPP.
Results: A total of 32 patients with AUR were included in the study. Patients with grade 3 IPP were found to have a significant failure rate compared to grade 1 (P = 0.022) and grade 2 (P = 0.041).
Conclusion: Intravesical prostatic protrusion is a useful predictor of success of TWOC in patients with AUR. Patients with grade 3 IPP on ultrasound would benefit from TWOC and warrant earlier definitive surgical treatment.

Ketamine can be abused as a recreational drug, and there has been a recent surge in its
usage. The effects of ketamine on the urinary system were unknown until the recent publication
of a few case reports. Many doctors are still unaware of this new clinical entity, termed ketamineassociated
ulcerative cystitis. We report a case that we encountered and discuss the diagnosis and
disease management in addition to a review of the literature.

BACKGROUND:
The urinary tract can be affected by both congenital abnormalities as well as acquired disorders, such ascancer, trauma, infection, inflammation, and iatrogenic injuries, all of which may lead to organ damage requiring eventualreconstruction. As a gold standard, gastrointestinal segment is used for urinary bladder reconstruction. However, one majorproblem is that while bladder tissue prevents reabsorption of specific solutes, gastrointestinal tissue actually absorbs them.Therefore, tissue engineering approach had been attempted to provide an alternative tissue graft for urinary bladderreconstruction.
METHODS:
Human adipose-derived stem cells isolated from fat tissues were differentiated into smooth muscle cells andthen seeded onto a triple-layered PLGA sheet to form a bladder construct. Adult athymic rats underwent subtotal urinarybladder resection and were divided into three treatment groups (n = 3): Group 1 (‘‘sham’’) underwent anastomosis of theremaining basal region, Group 2 underwent reconstruction with the cell-free scaffold, and Group 3 underwent reconstructionwith the tissue-engineered bladder construct. Animals were monitored on a daily basis and euthanisation wasperformed whenever a decline in animal health was detected.
RESULTS:
All animals in Groups 1, 2 and 3 survived for at least 7 days and were followed up to a maximum of 12 weekspost-operation. It was found that by Day 14, substantial ingrowth of smooth muscle and urothelial cells had occurred inGroup 2 and 3. In the long-term follow up of group 3 (tissue-engineered bladder construct group), it was found that theurinary bladder wall was completely regenerated and bladder function was fully restored. Urodynamic and radiologicalevaluations of the reconstructed bladder showed a return to normal bladder volume and function.Histological analysisrevealed the presence of three muscular layers and a urothelium similar to that of a normal bladder. Immunohistochemicalstaining using human-specific myocyte markers (myosin heavy chain and smoothelin) confirmed the incorporation of theseeded cells in the newly regenerated muscular layers.
CONCLUSION
Implantation of PLGA construct seeded with smooth muscle cells derived from human adipose stemcells can lead to regeneration of the muscular layers and urothelial ingrowth, leading to formation of a completelyfunctional urinary bladder.

BACKGROUND: Urinary tract is subjected to a variety of disorders such as urethral stricture, which often develops as a result of scarring process. Urethral stricture can be treated by urethral dilation and urethrotomy; but in cases of long urethral strictures, substitution urethroplasty with genital skin and buccal mucosa grafts is the only option. However a number of complications such as infection as a result of hair growth in neo-urethra, and stone formation restrict the application of those grafts. Therefore, tissue engineering techniques recently emerged as an alternative approach, aiming to overcome those restrictions. The aim of this review is to provide a comprehensive coverage on the strategies employed and the translational status of urethral tissue engineering over the past years and to propose a combinatory strategy for the future of urethral tissue engineering. METHODS: Data collection was based on the key articles published in English language in years between 2006 and 2018 using the searching terms of urethral stricture and tissue engineering on PubMed database. RESULTS: Differentiation of mesenchymal stem cells into urothelial and smooth muscle cells to be used for urologic application does not offer any advantage over autologous urothelial and smooth muscle cells. Among studied scaffolds, synthetic scaffolds with proper porosity and mechanical strength is the best option to be used for urethral tissue engineering. CONCLUSION: Hypoxia-preconditioned mesenchymal stem cells in combination with autologous cells seeded on a prevascularized synthetic and biodegradable scaffold can be said to be the best combinatory strategy in engineering of human urethra.

ABSTRACT
Erectile dysfunction (ED) is one of the common sexual disorders affecting many men worldwide.
Owing to shared common risk factors, periodontitis is related to ED. However, the prevalence of
periodontitis among Malaysian patients with ED is currently unknown. This study aimed to investigate
the prevalence of periodontitis in patients with ED in Malaysia and the factors associated with this
relationship. Forty-one subjects aged 27–59 years old were recruited to participate in this study.
The International Index of Erectile Function (IIEF-5) was used in assessing the presence of ED.
Their periodontal health was assessed through comprehensive periodontal examination including plaque
index, bleeding on probing and clinical attachment level. The subjects were categorised according
to the severity of their periodontal health and ED. A questionnaire on general health and oral habits
was administered. The prevalence of periodontitis (95.5%) among subjects with ED was significantly
higher than those without ED (52.6%). Subjects with ED had the worst periodontal health, as
indicated by the mean clinical attachment loss and percentage of sites with bleeding on probing.
No differences in oral hygiene habits were found between subjects with and without ED. The prevalence
of periodontal disease among Malaysian patients with ED was high. Periodontitis was positively
associated with the severity of ED, supporting a dose-dependent association between the two diseases.
Oral hygiene habits were not significantly related to any periodontitis parameters nor were significantly
different between subjects with and without ED.
