Predictive factors for percutaneous nephrolithotomy bleeding risks.

Objective: This study aimed to identify predictive factors for percutaneous nephrolithotomy (PCNL) bleeding risks. With better risk stratification, bleeding in high-risk patient can be anticipated and facilitates early identification. Methods: A prospective observational study of PCNL performed at our institution was done. All adults with radio-opaque renal stones planned for PCNL were included except those with coagulopathy, planned for additional procedures. Factors including gender, co-morbidities, body mass index, stone burden, puncture site, tract dilatation size, operative position, surgeon's seniority, and operative duration were studied using stepwise multivariate regression analysis to identify the predictive factors associated with higher estimated hemoglobin (Hb) deficiency. Results: Overall, 4.86% patients (n=7) received packed cells transfusion. The mean estimated Hb deficiency was 1.3 (range 0-6.5) g/dL and the median was 1.0 g/dL. Stepwise multivariate regression analysis revealed that absence of hypertension (p=0.024), puncture site (p=0.027), and operative duration (p=0.023) were significantly associated with higher estimated Hb deficiency. However, the effect sizes are rather small with partial eta-squared of 0.037, 0.066, and 0.038, respectively. Observed power obtained was 0.621, 0.722, and 0.625, respectively. Other factors studied did not correlate with Hb difference. Conclusion: Hypertension, puncture site, and operative duration have significant impact on estimated Hb deficiency during PCNL. However, the effect size is rather small despite adequate study power obtained. Nonetheless, operative position (supine or prone), puncture number, or tract dilatation size did not correlate with Hb difference. The mainstay of reducing bleeding in PCNL is still meticulous operative technique. Our study findings also suggest that PCNL can be safely done by urology trainees under supervision in suitably selected patient, without increasing risk of bleeding.

Prevalence of urolithiasis in Sarawak and associated risk factors: An ultrasonagraphy-based cross-sectional study.

Objective: The aim of this research is to study the prevalence of urolithiasis among the population of Sarawak Malaysia and the associated risk factors. Patients and Methods: A survey was conducted among individuals aged ≥18 years age in three primary health care clinics in the main cities of Sarawak from March 2019 to March 2020. Participants underwent face-to-face interview using a predesigned and standardised questionnaire. Details on demographic data, comorbidities, dietary variables and lifestyle were collected. Ultrasonographic examination of the kidney, ureter and bladder was performed followed by blood and urine sampling. Prevalence was defined as the proportion of participants with kidney stones, and univariate logistic regression was used to estimate the associated factors. Results: A total of 1087 participants (486 male, 601 female) completed the questionnaire. Ultrasonographic examination and laboratory investigation were carried out, with an overall response rate of 98.8%. The prevalence of ultrasonographic proven urolithiasis in the sample studied was 4.04%. The mean age of patients with urolithiasis was 50.05 (SD 14.6, range 18-89), and the male to female ratio was 1.2: 1. Univariate analysis showed that odd ratio of personal history of urolithiasis (0.16, p:0.00), salty food intake (0.39, p:0.02), family history of urolithiasis (0.39, p:0.01), and hypertension (1.77, p:0.04) was significantly associated with a greater risk of urolithiasis. Conclusion: The prevalence of urolithiasis in this study population is 4.04%. It affects males and females equally; 61.4% are in the age group of 25-64 years. Hypertension, high salt diet, personal history of urolithiasis and family history of urolithiasis are significant risk factors.

Self-perceived burden and its associations with health-related quality of life among urologic cancer patients.

OBJECTIVE: This study examined the prevalence of self-perceived burden (SPB) and its association with health-related quality of life (HRQoL) among urologic cancer patients. METHODS: This was a prospective, cross-sectional study. A total of 429 respondents diagnosed with urologic cancers (prostate, bladder and renal cancer) from Sarawak General Hospital and Subang Jaya Medical Centre in Malaysia were interviewed by using a structured questionnaire. SPB and HRQoL were measured by the Self-perceived Burden Scale and the Functional Assessment of Cancer Therapy-General 7 Item Scale respectively. RESULTS AND CONCLUSION: Self-perceived burden was experienced by 73.2% of the respondents. Respondents who had a lower education level, a monthly household income

Financial toxicity and its associations with health-related quality of life among urologic cancer patients in an upper middle-income country.

PURPOSE: This study examined the prevalence of financial toxicity (FT) and associated factors among urologic cancer patients. The association between FT and health-related quality of life (HRQoL) was also investigated. METHODS: A total of 429 respondents diagnosed with urologic cancers (prostate cancer, bladder and renal cancer) from Sarawak General Hospital and Subang Jaya Medical Centre in Malaysia were interviewed using a structured questionnaire. Objective and subjective FT were measured by catastrophic health expenditure (healthcare-cost-to-income ratio greater than 40%) and the Personal Financial Well-being Scale, respectively. HRQoL was measured with the Functional Assessment of Cancer Therapy - General 7 Items scale. RESULTS: Objective and subjective FT were experienced by 16.1 and 47.3% of the respondents, respectively. Respondents who sought treatment at a private hospital and had out-of-pocket health expenditures were more likely to experience objective FT, after adjustment for covariates. Respondents who were female and had a monthly household income less than MYR 5000 were more likely to experience average to high subjective FT. Greater objective FT (OR = 2.75, 95% CI 1.09-6.95) and subjective FT (OR = 4.68, 95% CI 2.63-8.30) were associated with poor HRQoL. CONCLUSIONS: The significant association between both objective and subjective FT and HRQoL highlights the importance of reducing FT among urologic cancer patients. Subjective FT was found to have a greater negative impact on HRQoL.

Management of advanced prostate cancer in a middle-income country: real-world consideration of the Advanced Prostate Cancer Consensus Conference 2017.

OBJECTIVE: To examine the results of the Malaysian Advanced Prostate Cancer Consensus Conference (MyAPCCC) 2018, held for assessing the generalizability of consensus reached at the Advanced Prostate Cancer Consensus Conference (APCCC 2017) to Malaysia, a middle-income country. METHODS: Six key sections were chosen: (1) high-risk localized and locally advanced prostate cancer, (2) oligometastatic prostate cancer, (3) castration-naïve prostate cancer, (4) castrate resistant prostate cancer, (5) use of osteoclast-targeted therapy and (6) global access to prostate cancer drugs. There were 101 consensus questions, consisting of 91 questions from APCCC 2017 and 10 new questions from MyAPCCC 2018, selected and modified by the steering committee; of which, 23 questions were assessed in both ideal world and real-world settings. A panel of 22 experts, comprising of 11 urologists and 11 oncologists, voted on 101 predefined questions anonymously. Final voting results were compared with the APCCC 2017 outcomes. RESULTS: Most voting results from the MyAPCCC 2018 were consistent with the APCCC 2017 outcomes. No consensus was achieved for controversial topics with little level I evidence, such as management of oligometastatic disease. No consensus was reached on using high-cost drugs in castration-naïve or castration-resistant metastatic prostate cancer in real-world settings. All panellists recommended using generic drugs when available. CONCLUSIONS: The MyAPCCC 2018 voting results reflect the management of advanced prostate cancer in a middle-income country in a real-world setting. These results may serve as a guide for local clinical practices and highlight the financial challenges in modern healthcare.

Fournier’s Gangrene: A Case of Neglected Symptoms with Devastating Physical Loss

Fournier’s gangrene is a severe life-threatening infection involving the perianal area, perineum, and external genitalia. It demands prompt recognition, critical care therapy, surgical therapy, and a combination of antibiotics. The infection commonly spreads via the fascial planes and causes superficial vascular thrombosis within the Colles’ fascia around the external genitalia. It can extend cephalad to involve the Scarpa’s fascia and Camper’s fascia in the abdominal wall. The treatment would include multiple debridements, which would result in disfiguring scars of the perineum and might lead to significant physical and psychological complications. We describe a case of a 58-years-old man presenting with Fournier’s gangrene resulting from an infection of an impacted urethral stone. The patient previously had obstructive voiding symptoms for 1 month but chose to neglect them. The resultant infection was severe and caused penile and right testicular gangrene. He underwent multiple wound debridements, which included a total penectomy and right orchiectomy. Psychological and rehabilitative support was necessary for him to overcome his loss and disfigurement.

Laparoscopic approach to small renal mass.

With maturing functional and oncologic outcomes data, open partial nephrectomy (OPN) has become the standard of care for T1a renal tumor. Laparoscopic approach can provide a speedier recovery with less blood loss and postoperative pain. Presuming adequate laparoscopic expertise, laparoscopic partial nephrectomy can provide equivalent oncologic outcome as for OPN albeit with higher urologic complications rate and longer warm ischemia time. With refinement of technique and use of robotic assistant, the shortcomings of laparoscopic approach can be further reduced. This article is a mini-review on the current status of laparoscopic approach to partial nephrectomy in the management of small renal mass.
