Abstract

Objective: To report our first experience laparoscopic living donor nephrectomy (LLDN). Material & Method: A 37 year-old man was planned for the living-donor transplantation. The recipient was a 63 year-old man sufferingfrom end stage renal disease, and hypertensive heart disease. The donor and recipient were allowed for positive qualification evaluated preoperatively. We applied a transperitoneal approach for the left kidney. Results: The operation time was 300 minutes and the estimated blood loss was 600 mL. The first warm ischemia time was 15 minutes and 24 seconds. There were no major intraoperative and postoperative complications. The donor began oral intake and mobilization within 10 hours and was hospitalized for 4 days. The recipient’s serum creatinine levels reached near baseline levels (1,5 mg/dL) at day 6. Conclusion: LLDN is technically feasible in Indonesia and may increase the rate of kidney donation in Indonesia due to the minimally invasive nature of the procedure.Keywords: Renal transplantation, laparoscopic living donor nephrectomy, Indonesia.

Abstract

The research was conducted to determine the hydrocarbon reservoir zone in the LIM-1 well, which was analyzed using quantitative and qualitative methods to assess the reservoir type involving several log data, including gamma ray (GR), neutron (NPHI), and density (RHOB). The quantitative analysis stage is the determination of hydrocarbon content by the crossover of NPHI log data, and RHOB log data with six target zones. The quantitative analysis stage in this study uses Interactive Petrophysics (IP) software version 3.5 on well LIM-1, also with target zone 1 only. The results obtained from qualitative and quantitative analysis at well LIM-1 show that there are three types of reservoirs in the study area from several target zones according to depth, which are dominated by oil, water, and gas.

Abstract

BACKGROUND The recurrence rate of kidney stone disease (KSD) can exceed 50% within 5 years. This study aimed to investigate factors associated with stone recurrence based on single nucleotide polymorphisms (SNPs) of the calcium-sensing receptor (CaSR) rs1801725 and rs1042636, demographic, and clinical profiles. METHODS We collected data on the demographic and clinical characteristics of 80 adult kidney stone formers from April 2021 to September 2022, including peripheral blood samples, morning and 24-hour urine, and 7-day water intake records. Real-time polymerase chain reaction was used to evaluate SNP. Comparisons were made between patients with recurrent and first-time stones. RESULTS 41% of 80 patients have experienced stone recurrence. Recurrent stone formers exhibited significantly higher 24-hour urine calcium excretion (p = 0.03) and lower serum calcium levels (p = 0.019) than first-time stone formers. Hypocitraturia (100%), low urine volume (78%), and hyperoxaluria (55%) were the main abnormalities of all patients. No significant differences were found in CaSR gene polymorphisms and other demographic, biochemical, or clinical parameters. CONCLUSIONS Recurrent stone formers had higher 24-hour urine calcium excretion and lower serum calcium levels. Other risk factors and CaSR polymorphisms may insignificantly affect KSD recurrence.

Abstract

This study aims to determine hydrocarbon zones and analyze petrophysics in the Sepinggan Formation, located in the lower Kutai Basin, which is one of the oil and gas producing formations in Indonesia. The data used includes 5 well log data and mudlog data. The results of the study show that the Sepinggan Formation has 14 potential zones dominated by carbonate sandstone lithology with a slight mixture of coal. Some key findings in the petrophysical analysis include the largest average shale volume of about 41% in zone 1 of well SPG-V8, the largest average porosity of about 24% in zones 1 and 2 of well SPG-V1, the largest average permeability of about 2591.08 mD in zone 1 of well SPG-V2, and the largest average water saturation of about 56% in zone 2 of well SPG-V7. Based on these results, further evaluation of hydrocarbon potential in the identified potential zones and optimization of exploration and exploitation techniques are needed to improve the efficiency of oil and gas production in the Sepinggan Formation.

Abstract

Volcanic rock reservoirs, characterized by fractures in their formations, have gained attention in Indonesia due to their oil content, particularly in the Jatibarang Formation in West Java. This study focuses on four wells in the West Java Basin containing the Jatibarang Formation, aiming to determine fracture intensity using conventional log data and to perform petrophysical analysis. The research employs well log, mud log, and core data, utilizing qualitative analysis to identify potential reservoir zones and quantitative analysis to calculate fracture intensity and petrophysical properties. The results show that fractures in the Jatibarang Formation can be identified through fracture intensity analysis using conventional log data (MSFL, RHOB, Caliper, PEF, and DT). Fracture intensity calculations were only carried out on the QB-3 well because the other wells did not have complete log data. The results of the fracture intensity analysis showed that the fractures that occurred in the QB-3 well had 1-23%. Petrophysical analysis of the four wells reveals that the cutoff values for clay volume (50%), porosity (10%), and water saturation (70%) indicate potential candidates for further reservoir research. The QB-3 well has seven potential zones with a fracture index value of more than 10%. Permeability in wells QB-3 and QB-4 is more than 60 mD, making these four wells potential candidates for further research on volcanic rock reservoirs.

Abstract

The double-J stent is one of the ureteral catheters with curved ends for fixation. Since its introduction in 1978, catheterisation using a double-J stent has become one of the most frequently performed procedures in urology. However, double-J stents may lead to various complications, causing patient discomfort, pain, and bladder symptoms. Technological advancements in stent design aim to minimise these complications and enhance comfort. This review aimed to determine the association between the material and design used in ureteral stents and complications in ureteral catheterisation. We conducted a systematic review following the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) checklist. Screening based on specific inclusion criteria was employed to select potential studies. A database search yielded a total of 124 studies. Nine full texts were evaluated for eligibility, resulting in the exclusion of one paper. Our findings indicate that ureteral stent insertion significantly increases the frequency of pain and urinary symptoms while decreasing overall health. The choice of materials and design plays a crucial role in minimising pain and improving the quality of life for patients. Physical properties such as firmness and tensile strength also affect the quality of life, with higher firmness and tensile strength causing lower quality of life. Stent material and design choice were context-dependent. Using soft stents and specialised soft distal pigtails has been shown to reduce patient stent-related symptoms. Silicone stents showed the least bladder symptoms than polymeric stents. Polymeric stents also showed no difference in utility from metallic stents for long-term usage.

Abstract

BACKGROUND Nephrolithiasis or kidney stone disease (KSD) is common worldwide. Despite various effective treatment strategies, KSD recurrence remains a problem. This study aimed to investigate the risk factors of KSD recurrence. METHODS This retrospective cohort study used medical records of all patients who came to the Department of Urology, Cipto Mangunkusumo Hospital, Jakarta, from January 2014 to December 2019, with asymptomatic and symptomatic KSD. Demographic information, clinical data, exposure to risk factors, and recurrent KSD diagnosis were collected. Univariate and multivariate analyses using logistic regression were performed to determine the significant risk factors. RESULTS We reported 325 patients with a median age of 52 years. More than half of the patients were males and from Java. Staghorn stone dominated the KSD types found in 181 patients (55.7%). After undergoing percutaneous nephrolithotomy, 214 patients (65.8%) became stone-free. However, about 40.6% of them later developed recurrent KSD. The adjusted odds ratio in recurrent KSD were 1.46 (95% confidence interval [CI] 1.33–1.59) for younger age, 1.86 (95% CI 1.61–2.07) for overweight–obese, 2.13 (95% CI 1.89–2.31) for less fluid intake, 1.81 (95% CI 0.97–2.12) for routine tea consumption, 1.24 (95% CI 1.06–1.84) for routine vegetables consumption, 2.27 (95% CI 1.83–2.84) for a family history of KSD, and 2.08 (95% CI 1.77–2.39) for diabetes mellitus (DM). CONCLUSIONS Most patients with recurrent KSD were younger, overweight/obese, had less fluid intake, a family history of KSD, and DM. Modifying a healthy lifestyle and a balanced diet is important to prevent KSD recurrence.

Abstract

BACKGROUND Ureteral stones are a common urological condition causing significant discomfort and morbidity. Medical expulsive therapy (MET) is a noninvasive approach to facilitate the passage of stones. This study aimed to compare the efficacy and safety of silodosin and tamsulosin as MET in patients with distal ureteral stones (DUS). METHODS We searched CINAHL, Cochrane Library, PubMed, and ScienceDirect for randomized controlled trials (RCTs) on the administration of silodosin and tamsulosin for DUS. The primary outcomes analyzed were stone expulsion rates and expulsion times, measured as risk ratio (RR) and mean difference (MD), respectively. Statistical analyses were performed using Review Manager 5.4 and STATA 17. RESULTS 14 RCTs comprising 1,535 patients (770 received silodosin) met the inclusion criteria. The silodosin group had notably higher stone expulsion rates (RR 1.20, 95% confidence interval [CI] 1.13–1.27, p<0.00001, I² = 37%), shorter expulsion times (MD −2.98, 95% CI −4.35–−1.62, p<0.01, I² = 85%), and fewer colicky pain episodes (MD −0.35, 95% CI −0.59–−0.10, p<0.01, I² = 83%) than the tamsulosin group. Retrograde ejaculation was the only adverse event that had a significant difference between both groups, statistically favoring tamsulosin (RR 1.61, 95% CI 1.12–2.33, p = 0.01, I² = 0%). CONCLUSIONS Silodosin should be preferred as the first-line MET agent for DUS owing to its better expulsion rate, shorter stone expulsion time, and fewer colicky pain episodes. However, tamsulosin may be used in selected cases where patients experience retrograde ejaculation after receiving silodosin.

Abstract

Lapangan "Alfa" yang terletak pada Formasi Attaka di Cekungan Kutai, Kalimantan Timur, memiliki potensi hidrokarbon pada zona shallow dan deltaic dengan litologi dominan batupasir dan batugamping. Penelitian ini bertujuan untuk melakukan karakterisasi reservoir guna mengidentifikasi zona-zona potensial hidrokarbon dan menentukan nilai properti petrofisikanya. Analisis dilakukan dengan mengintegrasikan data dari empat sumur, meliputi data well log (triple combo), mud log, dan core. Metode penelitian menggabungkan analisis kualitatif melalui quick look interpretation untuk identifikasi awal zona prospek, yang dilanjutkan dengan analisis kuantitatif menggunakan perangkat lunak petrofisika untuk menghitung parameter reservoir seperti volume serpih, porositas, permeabilitas, dan saturasi air. Hasil analisis kualitatif menunjukkan adanya 5 zona potensial dari total sumur yang dievaluasi. Berdasarkan analisis kuantitatif lebih lanjut, 3 zona di antaranya direkomendasikan sebagai kandidat untuk Drill Stem Test (DST). Zona-zona kandidat ini menunjukkan karakteristik reservoir yang menjanjikan dengan rata-rata porositas 18-28% (baik-istimewa), permeabilitas 27.2–261 mD, dan saturasi air 47–53%. Penentuan ini didasarkan pada nilai batas (cut-off) asumsi: porositas >18%, volume serpih <46%, dan saturasi air <53%, yang mengonfirmasi prospek hidrokarbon yang signifikan di lapangan penelitian
