Factors associated to hemoglobin decrease after percutaneous nephrolithotomy: a retrospective study.

OBJECTIVE: This study aims to determine the preoperative and perioperative risk parameters associated with a decrease in hemoglobin (Hb) in patients undergoing percutaneous nephrolithotomy (PCNL). METHODS: We collected prospective data of consecutive patients who underwent PCNL from January 2018 to December 2022. The median decrease in post-operative hemoglobin levels compared to pre-operative was found to be 1.5 g/dl. This value was the cut-off value that divided the sample into two groups. Group 1 has a decrease in Hb levels that is higher or equal to the cutoff, group 2 has a decrease in Hb levels that is lower than the cut-off. All preoperative, stone characteristics and perioperative factors were recorded. RESULTS: A total of 273 patients were included in the study, 141 in Group 1 and 132 in Group 2. The mean age of Group 1 was significantly higher (55.48 ± 8.73 vs 45.9 ± 10.75 years, p < 0.05). The mean bleeding of Group 1 was significantly higher (285.85 ± 113.68 vs 135 ± 77.54 ml, p < 0.05). There was a significant difference in mean operation time between groups (86.35 ± 32.05 vs 64.89 ± 27.83 min, p < 0.05). Multivariate analysis showed that the variables age, comorbid diabetes mellitus, intraoperative bleeding amount, and operation time had a significant relationship with Hb reduction in patients undergoing PCNL (p < 0.05). CONCLUSIONS: Older age, comorbid diabetes mellitus, large amounts of intraoperative bleeding, and longer operating time are factors associated with PCNL-related postoperative hemoglobin decrease.

Giant stone in a urinary bladder diverticulum in a 69-year-old male: a case report.

The stone formation could occur due to urine stasis in the bladder diverticulum. However, the stones are usually smaller in size and can pass spontaneously. However, a giant stone inside vesical diverticulum is considered a rare entity. We report a 69-year-old male, with a two-year history of lower urinary tract symptoms along with a recurrence of urinary tract infection. An abdominal computed tomography scan revealed the presence of a giant bladder diverticulum and a large bladder stone. The patient underwent a transurethral bladder neck incision followed by diverticulectomy with stone extraction. The diverticulum size measures 6x4x3.8 cm and diverticulum stone size of 4x3x3 cm. Fortunately, the patient recovered well after the operation. In conclusion, giant stones inside large vesical diverticulum are a rare occurrence and should be considered in patients with lower urinary tract symptoms. Early diagnosis and optimal management of the obstruction are the principles to prevent long-term complications.

Intrauterine device (IUD) migration into the bladder with stone formation: A case report.

Intrauterine device (IUD) is one of the most effective and standard contraception methods worldwide, including in Indonesia. A 54-year-old woman with frequent urination, pain in urination, and intermittency. History of using IUD 19 years ago. Urinalysis revealed there are pyuria and positive occult blood urine exam. Urinary sediment evaluation revealed some erythrocytes, leukocytes, and epithelial cells. Abdominal non-contrast CT scan revealed a stone with IUD. Stone and IUD were extracted via cystolithotomy. IUD complications may develop into bladder stone formation caused by IUD migration to the bladder. Stone extraction relieves symptoms and gives a good prognosis.
