RESUMO
Objective Since 1990, when the first laparoscopic nephrectomy was performed, there has been a dramatic increase in interest in laparoscopic procedures in urological surgeries.The aim of the study was to present our experience with the first 100 cases of laparoscopic nephrectomy at our institute, identify the difficulties encountered, and discuss how to approach the solutions. Materials and methods The data of all patients who underwent laparoscopic nephrectomy between May 2017 and April 2019 (n=100) were reviewed retrospectively. Results A total of 100 patients (49 men and 51 women), with a mean age of 34.1 ± 15.1 years, underwent laparoscopic nephrectomy. The mean operative time was 108 min (IQR, 45-240). The operative time was significantly reduced with the surgeons' experience. Of 100 cases, only four were converted to open surgery because of bleeding from the renal bed area, strong adhesions from previous surgeries, or morbid obesity. Of 100 patients, 30 were allowed intake on the same operative day while 70 were allowed on the first postoperative day. Intravenous and oral analgesics were discontinued on the second postoperative day in 81 patients. Conclusion The learning curve in our series of cases is comparable to a very similar studywith reduced operative time, reduced blood loss, and fewer complications when compared to open nephrectomy. In addition, setups with minimal previous laparoscopic units can initiate laparoscopic procedures with minimal risk to the patient.
RESUMO
OBJECTIVE: To determine the awareness of risk factors for bladder cancer and false beliefs associated with this disease. METHODS: This cross-sectional study was conducted at the Kidney Centre, Karachi, from January to February 2015, and comprised subjects who presented to the various in-house clinics. The subjects were interviewed using a questionnaire comprising demographic parameters, level of education and awareness of smoking hazards, knowledge and false beliefs associated with bladder cancer. A pilot study was performed prior to the main study and the questionnaire was redesigned accordingly. SPSS 20 was used for data analysis. RESULTS: Of the 1,000 respondents, 593(59.3%) were males and 407(40.7%) were females. Moreover, 229(22.9%) respondents were aware of the association between smoking and bladder cancer compared to 858(85.8%) who knew that there is an association between smoking and lung cancer. Besides, 479(47.9%) respondents said that smoking caused tuberculosis. Patients with a higher level of education were statistically more likely to be aware of the association between smoking and bladder cancer, i.e. 91(9.1%) uneducated, 208(20.8%) primary, 182(18.2%) secondary, 222(22.2%) intermediate and 352(35.2%) graduates (p=0.0001). Most common fallacy associated with bladder cancer was low intake of water 504(50.4%), followed by multiple sexual partners 362(36.2%). CONCLUSIONS: Most patients were unaware of the relationship between bladder cancer and tobacco smoking.
