A Prospective Study

Objectives Bleeding is the most common complication of percutaneous nephrolithotomy (PCNL). Injudicious transfusion is frequently performed in current practice, even though it is not always needed. This study aimed to identify the predictive factors of blood loss in the PCNL procedure and evaluate the perioperative transfusion practice. Methods A prospective study of PCNL was randomly performed by two consultants of endo-urology at our institution. The inclusion criteria were adults with kidney pelvic stones >20 mm or stone in inferior calyx >10 mm or staghorn stone. Those with coagulopathy, under anti-coagulant treatment or open conversion were excluded. A full blood count was taken at baseline and during 12, 24, 36, 72-hours post-operatively. Factors such as stone burden, sex, body surface area, shifting of hematocrit level and amount of blood transfused were analyzed statistically using line regression to identify the predictive factors of total blood loss (TBL).   Results Eighty-five patients were enrolled in this study. Mean TBL was 560.92 ± 428.43 mL for both endo-urology surgeons. Stone burden was the most influential factor for TBL (p=0.037). Our results revealed that TBL (mL) = -153.379 + 0.229 × stone burden (mm2) + 0.203 x baseline serum hematocrit (%); thus considerably predicted the need for blood transfusion. A total of 87.1% patients did not receive perioperative transfusion, 3.5% received intra-operative transfusion, 7.1% received post-operative transfusion, 23% had both intra and post-operative transfusion, resulting in a cross-matched transfusion ratio of 7.72. Mean perioperative blood transfused was 356.00 ± 145.88 mL.

BACKGROUND: In the age of modern medicine, thanks to the development of small-caliber nephroscope as well as various types of intracorporeal lithotripters, treatment options for renal stones have changed dramatically, and the area of percutaneous nephrolithotomy (PCNL) has expanded. Nowadays, PCNL is not only the first choice in the treatment of stones >2 cm, as well as complicated renal stones (staghorn stones, multiple stones, and stones associated with abnormal renal anatomy), but is also the method of optimal treatment for medium-sized stones not treated with other less invasive methods. AIM: The purpose of this study is to assess the efficacy and safety of PCNL as monotherapy in the treatment of renal stones larger than 15 mm. MATERIALS AND METHODS: This study presents a retrospectively prospective study of 14 (4 retrospective and 10 prospective) consecutive patients with renal stones larger than 15 mm treated with PCNL in the period from January 2020 to March 2020 at the GH “8 September” – Skopje. Pre-operative preparation of patients included: A history along with physical examination, a complete blood count and radiological examinations to assess the size of the stones, the anatomical features of the kidney and its function, and to accurately plan the operative approach. PCNL was performed in the prone-position; lithotripsy was performed with a double, pneumatic and ultrasonic intracorporeal lithotripter Swiss LithoClast Master with the use of the Karl Storz 24–26 fr nephroscope. Postoperatively, patients were monitored on the 1st, 7th, and 30th post-operative day, determining the demographic and clinical characteristics, the efficacy of PCNL, perioperative blood loss, the duration of the operative procedure, the duration of hospital stay, and the resulting intraoperative and post-operative complications. RESULTS: The study included eight men (57.1%) and six women (42.8%). The mean age of the patients was 52.35 ± 11.00. In 5 (35.71%) patients, the stones were localized in the left kidney, and in 9 (64.28%) patients in the right kidney. The average body mass index was 25.11 ± 3.92 kg/m². The average area of the stones was 371.24 ± 131.86 mm². Eleven (78.57%) patients had simplex stones, while 3 (21.42%) had complex stones (staghorn stones and multiple stones). The stones were localized in the renal pelvis, upper, middle, and lower calyx at 5 (35.71%), 2 (14.28%), 4 (28.57%), and 3 (21.42%) patients, respectively. The mean value of pre- and post-operative serum hemoglobin was 13.94 ± 1.00 g/dl and 11.77 ± 1.51 g/dl, respectively. The effectiveness of the procedure on the 1st post-operative day assessed by ultrasound diagnostics and kidney-ureter-bladder X-ray was 78.57%. The success rate on the 30th post-operative day after additional procedures was 92.85%. The average operating time in the entire series was 119.28 ± 9.42 min. The average hospital stay was 5.57 ± 1.11 days. The average operative blood loss was 2.19 ± 0.88 g/dl. CONCLUSION: The results of this retrospectively prospective study confirm that PCNL is a minimally invasive, safe, and effective method for removing renal stones. This method, with the development of new technologies, has an increasingly important role in the modern surgical treatment of nephrolithiasis. PCNL can also be performed in the early stages of the learning curve without compromising patient safety and treatment benefits. The procedure is safe and effective, performed even by less experienced urologists if the protocols established for this procedure are followed. This can achieve a rate of success comparable to most established standards without causing major complications.

Objective: To study the various beliefs and problems regarding menstruation among adolescent girls living in rural border areas. Design- Prospective study. Setting- Pediatric outpatient clinic. Materials and methods- About 200 adolescent girls (11-19 years) living in rural border areas were enrolled for the study. These girls were asked about menarche, duration of the cycle, amount of blood loss and the various menstrual problems. They were also asked about the various beliefs and myths regarding menstruation. The girls having any illness affecting the menstrual cycle or those suffering from neuropsychiatric disorders were excluded from this study. Results- About 51% of the study population was in the age group 17-18 years. About 43.5% of girls attained menarche at the age of 10-12 years. About 51% of girls did not know about menstruation before menarche. Abdominal pain was the most common side effect seen in 41% of girls during menstruation. About 61% of girls considered themselves unclean during menstruation.  Twenty percent avoided schools, 20% avoided kitchen, 12% avoided temples while 10% stayed away from friends/ relatives. Only 33% of girls knew that menstruation stops temporarily after becoming pregnant. Twenty-two percent girls were using sanitary napkins while the rest used different types of clothes during the menstrual cycle. Conclusion- There is a dire need to educate girls regarding menstruation before menarche in the rural border areas. Every mother should discuss in a friendly way regarding various aspects of menstruation.

The aim of this paper is to assess the efficiency and safety of the tranexamic acid in reducing blood loss and the need for transfusion in patients diagnosed with staghorn calculi treated by percutaneous nephrolithotomy. Percutaneous nephrolithotomy (PCNL) is a minimally invasive technique used for large kidney stones. Hemorrhagic complications and urinary sepsis are serious complications associated with this type of surgery. Tranexamic acid is an antifibrinolytic drug that has the property of reducing intra or postoperative bleeding. The experience with tranexamic acid in preventing blood loss during percutaneous nephrolithotomy for is limited. The use tranexamic acid in percutaneous nephrolithotomy for staghorn type stones is safe and is associated with reduced blood loss and a lower transfusion rate.
