Our understanding of interstitial cystitis/bladder pain syndrome (IC/BPS) has evolved over time. The diagnosis of IC/BPS is primarily based on symptoms such as urgency, frequency, and bladder or pelvic pain. While the exact causes of IC/BPS remain unclear, it is thought to involve several factors, including abnormalities in the bladder’s urothelium, mast cell degranulation within the bladder, inflammation of the bladder, and altered innervation of the bladder. Treatment options include patient education, dietary and lifestyle modifications, medications, intravesical therapy, and surgical interventions. This review article provides insights into IC/BPS, including aspects of treatment, prognosis prediction, and emerging therapeutic options. Additionally, it explores the application of deep learning for diagnosing major diseases associated with IC/BPS.

Purpose: This paper proposes a technological system that uses artificial intelligence to recognize and guide the operator to the exact stenosis area during endoscopic surgery in patients with urethral or ureteral strictures. The aim of this technological solution was to increase surgical efficiency. Methods: The proposed system utilizes the ResNet-50 algorithm, an artificial intelligence technology, and analyzes images entering the endoscope during surgery to detect the stenosis location accurately and provide intraoperative clinical assistance. The ResNet-50 algorithm was chosen to facilitate accurate detection of the stenosis site. Results: The high recognition accuracy of the system was confirmed by an average final sensitivity value of 0.96. Since sensitivity is a measure of the probability of a true-positive test, this finding confirms that the system provided accurate guidance to the stenosis area when used for support in actual surgery. Conclusions The proposed method supports surgery for patients with urethral or ureteral strictures by applying the ResNet-50 algorithm. The system analyzes images entering the endoscope during surgery and accurately detects stenosis, thereby assisting in surgery. In future research, we intend to provide both conservative and flexible boundaries of the strictures.

Medical AI research and development have been largely focused on diagnosis, prediction, treatment, and management as an auxiliary means of patient care. AI is mainly used in the fields of personal healthcare and diagnostic imaging. In urology, substantial investments are being made in the development of urination monitoring systems in the personal healthcare field and diagnostic solutions for ureteral stricture and urolithiasis in the diagnostic imaging field. This paper describes AI applications for urinary diseases and discusses current trends and future perspectives in AI research.

BACKGROUND: The angiotensin converting enzyme(ACE) is a key component of the renin-angiotensin system thought to be important in the pathogenesis of hypertension and cadiovascular diseases. Deletion polymorphism in the ACE gene may be a risk factor for myocardial infarction. The insertion/deletion(I/D) polymorphism of the ACE detected by PCR analysis appears to be associated with hypertension in Koreans and its nucleotide was subcloned into T-vector and its nucleotide sequences were determined. We also examined an association between hypertension and genetic variance of ACE. METHODS AND RESULTS: We identified the angiotensin I-converting enzyme genotype in 127 hypertensive and 189 normotensive Korean subjects. The distribution of ACE genotype II, ID, DD were 39.2%, 40.2%, 20.6% respectively and the frequency for ACE alleles I and D were 0.593 and 0.407, respecively in all subjects. The frequency of D allele in Korean males is higher than that of Korean females(male; 0.438 : female; 0.267), and the frequency of I allele in Korean females is higher than that of Korean males(female; 0.733 : male; 0.562). Genotype distributions of angiotensin I-converting enzyme genes in Korean normal adult population were different from that of Caucasians(P<0.001). There were no significant differences in genotype frequency between the hypertensive control group(n=127) and the normotensive group(n=189). CONCLUSIONS: We observed significant differences of ACE genotype distribution between the male group and the female group in total(P=0.001) and in hypertensive Korean subjects(P=0.013).

PURPOSE: Natural orifice transluminal endoscopic surgery (NOTES) is a new surgical option using endoscopic advancement to the peritoneal cavity through the stomach, colon, vagina, or urinary bladder without an abdominal wall scar (incision). The aim of this study was to assess the feasibility of transgastric gastroscopic intra-abdominal exploration with gastric incision and closure before the NOTES would be done. METHODS: Under general anesthesia of a female dog, one-channel gastroscope was advanced to the stomach and the lumen was irrigated with anti-bacterial solution. The anterior wall of the antrum was incised by about 1 cm with a needle knife; then, the gastroscope was advanced into the peritoneal cavity. An exploration of the entire intra-abdominal cavity was performed. RESULTS: We were able to evaluate the stomach, the greater omentum, the diaphragm, the peritoneum, the urinary bladder, the bowel, the spleen, the liver, the gallbladder, the uterine horn, the uterine body, and the vagina, but could not evaluate the ovary, the kidney, and the pancreas. The observation of the abdominal cavity was followed by the gastric wall closure with a 135o endoclip. The dog was recovered after confirmation of secure closure of the incision site. CONCLUSIONS: Transgastric incision, closure, and abdominal exploration are feasible without an abdominal wall scar, and the NOTES can be one option for future abdominal operations in humans and needs to be further investigated.

To evaluate the maternal and fetal effects of propanidid, clinical observations were carried out in 160 cases of Cesarean section out of 4, 230 deliveries made during the past three years. Upon having the obstetricians ready for incision, 10ml. of 5 per cent propanidid and 40mg. of succinylcholine chloride were administered intravenously, and surgery was begun almost simultaneously with endotracheal intubabation. Thereafter, anesthesia was maintained with N2O-O2-fluothane, N2O-O2 -ether, or ether-O2 in semiclosed circle absorption system. Umbilical cord was ligated within 3-5 minutes after the commencement of induction. This method of anesthesia did not seriously affect the maternal respiration or circulation, and Apgar scores were good or fair in the majority of cases. No undesirable side effects or complications directly attributable to propanidid were encountered.

PURPOSE: Distraction osteogenesis has been applied to the maxillofacial implantology and good experimental and clinical results have been reported. However, histologic studies of implants placement on distraction osteogenesis of atrophic alveolar ridges are scarce. In this study, we compare the bone formation between in the transport part and in the distraction part by histomorphometric analysis. MATERIALS AND METHODS: Three adult beagle dogs were served as experimental subjects. The 2 premolars and 1st molar were extracted on the Lt. side of mandible in each beagle dog. After one month later, osteotomy was performed and distraction device was adapted. Distraction was performed with gradual incremental separation of two bone pieces at a rate of 1.0mm per day for 5 days. During consolidation phase, new bone was formed in the distraction zone between the separated bone pieces. 5 weeks after distraction phase, 3 implants were placed in each beagle dog. The implants were inserted through transport part and distraction part and inferior basal bone. The animals were sacrificed at 2 weeks, 4 weeks, and 12 weeks after implant placement. BIC and BA of implants on distraction part and transport part were measured histomorphometrically. RESULTS: BIC, BA increased after implant placement as time goes by passes and new bone formation was slightly higher in transport part than in distraction part at 2 weeks, 4 weeks after implant placement. At 12 weeks after implant placement, BIC, BA of were 74%, 61% in transport part and 77%, 59% in distraction part, therefore there were no difference in BIC and BA between transport part and distraction part at 12 weeks after implant placement.

OBJECTS: The purpose of this study is to estimate the values of foot pressure of the stance phase during a gait cycle in hemiplegic gait. METHOD: Thirty patients who had a stroke and forty healthy adults were evaluated by the EMED-SF system to analyze the stance phase of hemiplegic gait. The stance phase was evaluated by 6 points according to the foot pressure and center of pressure proposed by Lee et al.2) RESULTS: 1) In hemiplegics, the stance time of involved limb decreased compared with that of the uninvolved limb and increased that of control groups (p<0.05). 2) In hemiplegics, the midstance time increased but the loading response and terminal stance decreased compared with the uninvolved limb and controls (p<0.05). 3) In hemiplegics, the midstance time decreased and the loading response and terminal phase increased according to the increased Brunnstrom stage (p<0.05). CONCLUSION: The results showed that an analysis of stance phase by the measurement of plantar pressure was a valuable parameter in the gait analysis of hemiplegic patients.

A 30-year-old female patient presented with a progressive gait disturbance, who had been previously diagnosed for cataract and ovarian failure. Brain magnetic resonance imaging showed a high signal intensity of white matter in fluid attenuated inversion recovery and low signal intensity in brain volume imaging, suggesting demyelinating leukodystrophy. Genetic analysis confirmed the pathogenic homozygous mutations c.245T>A in the EIF2B2 gene, which is associated with vanishing white matter disease.
